What if you really believed that God is 100% for you? That he not only accepts you, but accepts you fully, because of the perfect person and work of his Son? That your best successes cant earn you any more access, and your worst failures cant take any of it away? If you did really did it might change everything for the pursuit of joy in your life. The Christian doctrine that deals with Gods acceptance of us into right relationship with him is called justification. Its the long j-word that has so much to do with the short j-word that were all seeking in our own way: joy.
Justification by Faith Alone
Justification deals with how we get right with God. Here the setting is the law court. Theres a defendant (you), and theres a Judge (God). And were all rightly charged with unrighteousness a treasonous offense against the Judge himself.
To be justified means that the Judge declares you righteous, rather than guilty. It means to be cleared of any wrongdoing. The remarkable thing, according to the Christian gospel, is that even though we truly are guilty, God justifies the ungodly through faith (Romans 4:5).
On what basis, though, does God declare us righteous? Its been a major controversy for nearly 500 years. Some have claimed that our full acceptance by God is based not only on the work of Christ outside of us, but also on the Holy Spirits work in us. God infuses us with righteousness and declares us righteous with that in view.
Others have claimed more in line with the New Testament that Gods full acceptance of us is owing to the righteousness of another, Jesus Christ (1 John 2:1). We are declared righteous, and fully accepted by God, not on the basis of any righteousness in us, but only through faith, looking outside ourselves and joining us to a righteousness not of our own doing Jesus who is our righteousness (1 Corinthians 1:30; Romans 5:19; 10:4; 2 Corinthians 5:21).
This justification by faith alone is at the very heart of the gospel. Martin Luther called it the doctrine on which the church stands or falls. And those who most deeply hold to justification by faith alone become the worlds freest people, truest lovers, and greatest doers, all because they have found a greater and deeper capacity and potential for joy.
His Righteousness, Our Rejoicing
One key biblical passage for why justification by faith alone is essential for true joy in God is Philippians 3:1 and the verses that follow.
In chapter 2, Paul stressed that it is joy that keeps him going in the ministry, and joy that he hopes inspires the Philippians to pursue unity and humility. He returns to that theme of joy a few verses later as he turns to address the orientation of the church toward her enemies.
Rejoice in the Lord (Philippians 3:1) is not only the connection to what has come before, but it is a banner that flies over the section that follows. This is no simple segue. This is the very thing that will separate true believers from religious posers. Paul focuses in on what binds the church together, and gives her the wherewithal to stand firm in the face of opposition: joy in Jesus. Rejoice in the Lord.
The main contrast Paul makes here between the church and her opponents is the varying sources of their confidence. The opponents confidence, for right-standing with God, is in their own performance, but the true people of God put no confidence in the flesh (Philippians 3:3). Not some confidence in the flesh, but no confidence in the flesh. In other words, they embrace justification by faith alone. Whatever grounds they might have for confidence in self, they have pushed that aside to glory in Christ Jesus (Philippians 3:3). Gods acceptance of them is totally based on Christ.
We cannot be truly happy unless Gods acceptance of us is totally based on Christ.
Not Your Pedigree or Performance
Paul embraced this reality with humility and boldness. If he was tempted to lean on his own pedigree and performance, he had just about anyone imaginable outdone (Philippians 3:46). But rather than trusting in his record of right-doing, Paul has been given life and liberty in the gospel for the surpassing pursuit of happiness. All his impressive gains he has counted as loss,
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 3:89)
Joy in God, then, is inextricably linked to justification by faith alone. The surpassing worth of knowing Christ Jesus my Lord will not be fully enjoyed apart from being joined to Jesus by faith and having his righteousness, which far surpasses our own, as the only grounds of Gods acceptance of us. A robust, solid embrace of justification by faith alone is essential for the life of Christian joy.
