How Good Is Good Enough? What Jesus Teaches About True Righteousness

One of the most pressing questions people wrestle with, inside and outside the church, is whether they are living a good enough life. Jesus addresses this question head-on in the Sermon on the Mount, and His answer is both challenging and deeply freeing.

What Is the Sermon on the Mount and Why Does It Matter?

The Sermon on the Mount, found in Matthew chapters 5 through 7, was preached to a mixed crowd. Some were devoted followers of Jesus. Others were skeptics. Some outright opposed Him. But nearly all of them shared one burning question: how good is good enough?

That question is just as relevant today. Jesus does not sidestep it. He answers it directly, and His answer reshapes everything we think we know about righteousness.

Did Jesus Come to Get Rid of the Old Testament Law?

Many people in Jesus' day assumed He was tearing down everything the Old Testament stood for. Jesus corrects that assumption immediately in Matthew 5:17-18:

"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished." - Matthew 5:17-18 English Standard Version (ESV)

Jesus did not come to dismantle the Old Testament. He came to fill it up, to bring it to its full and complete meaning. Think of it like a container being filled to the brim. Jesus came to fill the law so that we could better understand it and apply it to our lives.

How the Entire Old Testament Points to Jesus

When you look closely at the Old Testament, a clear pattern emerges. Every major event and story points forward to the cross of Jesus Christ.

- Genesis 3: After Adam and Eve sinned, God made a blood sacrifice to cover them. Jesus shed His blood on the cross for our sins.

- Noah's Ark: Those who entered the ark were saved from God's judgment. Those who enter into Christ are saved from the judgment of hell.

- Abraham and Isaac: God provided a substitute lamb at the last moment. Jesus is our substitute, dying in our place so we do not have to.

- The Exodus: Israel escaped the enemy through the Red Sea. In Christ, we too can overcome the enemy in our lives.

- The Tabernacle: God dwelled among His people. Through Christ, God now dwells within every believer.

Jesus fulfilled all of it, most completely through His death, burial, and resurrection.

Is Truth Eternal or Does It Change With the Times?

We live in a culture where truth seems to shift depending on who holds power or influence. But Jesus makes clear that the law of God operates on God's timetable, not ours, and that timetable is rooted in the eternal character of God Himself.

God is not simply the source of truth or the conveyor of truth. He is truth. He is righteousness itself, embodied in His very person. Because God is eternal, righteousness is eternal. What is right and wrong does not change, because it is rooted in who God is, not in the opinions of any era or culture.

As Psalm 19:1 reminds us: "The heavens declare the glory of God, and the sky above proclaims His handiwork." - Psalm 19:1 English Standard Version (ESV)

And 1 John 1:5 puts it plainly: "This is the message we have heard from him and proclaim to you, that God is light, and in Him is no darkness at all." - 1 John 1:5 English Standard Version (ESV)

Truth is not something we bend to fit the current moment. It is something we return to, again and again, as the foundation for how we live.

What Does It Mean to "Relax" the Law of God?

In Matthew 5:19, Jesus warns against relaxing even the least of God's commandments. This is not just a warning for pastors and teachers. Every believer influences others, whether they realize it or not. Children, grandchildren, neighbors, coworkers, and friends are all watching how we live.

When we pick and choose which parts of God's Word we will follow, we diminish our witness and our influence in the kingdom of God. Jesus says those who practice and teach God's commands will be called great in the kingdom of heaven. That greatness is not about pride or self-promotion. It is the quiet, faithful result of a life surrendered to truth.

Why Religious People Are Not Automatically Righteous

Jesus delivers one of His most striking statements in Matthew 5:20:

"For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven." - Matthew 5:20 English Standard Version (ESV)

The scribes and Pharisees were the most visibly religious people of their day. If their righteousness was not enough, who could possibly measure up? That is exactly the point. No one can. Not on their own.

Jesus is not calling us to try harder. He is exposing the impossibility of earning righteousness through outward performance. A whitewashed exterior cannot cover inward corruption. True righteousness must come from somewhere else entirely.

What Is the New Covenant and How Does It Change Everything?

Centuries before Jesus walked the earth, the prophet Jeremiah foretold a new covenant that God would make with His people. Jeremiah 31:33 says:

"For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people." - Jeremiah 31:33 English Standard Version (ESV)

Under the old covenant, the law was written on stone tablets. Hard, rigid, external. Under the new covenant, God writes His law on the hearts of His people. This is not a loosening of the standard. It is a transformation of the person.

Hebrews 10:15-18 confirms that this prophecy was fulfilled through Jesus Christ. Through His death, our sins are forgiven, past, present, and future. And because of that forgiveness, we no longer have to spend our lives trying to prove how good we are. Jesus answered the question of how good is good enough. He is good enough, in our place.

How Does the Holy Spirit Write God's Law on Our Hearts?

When a person trusts in Jesus Christ, they receive the Holy Spirit. And it is the Holy Spirit who produces in us what the law always pointed toward. Galatians 5 describes this as the fruit of the Spirit: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.

None of us can manufacture these qualities on our own. But as we surrender to the Holy Spirit, He produces them in us from the inside out. That is what it means for the law to be written on the heart.

The Apostle Paul understood this deeply. In Philippians 3:8-10, he writes:

"Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in Him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith." - Philippians 3:8-9 English Standard Version (ESV)

Paul counted his own religious achievements as worthless compared to the righteousness that comes through faith in Christ. That is the posture God calls every believer to take.

Can Anyone Live a Perfectly Righteous Life?

Not on this side of heaven. But that is not the goal. The goal is surrender. As we follow Jesus on the narrow path, we are transformed from the inside out. Our outward behavior begins to reflect what God has placed within us. We become a light in a world full of darkness, not because we have perfected ourselves, but because we have surrendered to the One who is perfect.

Truth exists. It is not a matter of opinion or cultural consensus. It is embodied in the person of God Himself, and it is available to every person who comes to Him in faith.

Life Application

This week, stop trying to answer the question "how good is good enough" on your own terms. Instead, take an honest look at where you may be relying on outward performance or religious routine rather than genuine heart surrender to Jesus Christ.

Ask yourself these questions:

• Am I trying to earn God's approval through my behavior, or am I resting in the righteousness that Christ has already provided for me?
• Are there areas of God's Word that I have been quietly setting aside because they feel too difficult or inconvenient?
• Am I allowing the Holy Spirit to produce His fruit in my life, or am I relying on my own effort to appear righteous to others?
• Who in my life is watching how I live, and what truth am I communicating to them through my daily choices?

The narrow path is not about being perfect. It is about being surrendered. Choose one area this week where you will stop striving in your own strength and instead ask the Holy Spirit to do what only He can do in your heart.
