* The ungodly are justified through faith (Romans 4:4-6).
* Christ died for the ungodly (Romans 5:6-10).
Does this mean that it is permissible for a Christian to continue living in sin after conversion? Absolutely not. Consider the following points of Paul's argument:
* The Law is upheld by our faith (Romans 3:31).
* Christians are to put to death fleshly works through the Spirit (Romans 6:1-2).
* The truth sets us free from the shackles of sin (Romans 6:17-18).
The Christian walk is a call to put away the deeds of the flesh. Our conscience has been purified by the blood of Christ to serve the living God. The Christian walk is a higher calling, firmly established on the foundation of our Lord Jesus Christ. We have been called to walk humbly with God. We have been called to faithfully serve God.
The very reason that boasting is excluded from justification is that we are all sinners. We are not deserving of salvation. Even Christians still have spiritual weaknesses. We are still subject to temptation. We need the righteousness of God. He is gradually conforming our character to that of Jesus Christ. God has saved us in spite of our sins.
It may sound noble or pious to deny that we are sinners saved by His grace, but such a notion could not be further from the truth (1 John 1:7-10). In fact, Jesus instructed His disciples to pray for the forgiveness of sin on a daily basis (Matthew 6:11-13). If we sin, then we have Jesus Christ as our advocate before the Father (1 John 2:1). Other passages of Scripture confirm that the righteous do occasionally stumble (Psalms 130:3-4; Proverbs 20:9; Ecclesiastes 7:20; James 3:2).
To deny that we are sinners saved by the grace of God is the preaching of a false gospel and calling God a liar. Our sin nature does not immediately disappear in its totality at the moment of conversion. Christians are called saints because they have been consecrated by the Holy Spirit. We are not to continue in sin. We have been called to grow in sanctification. It is the grace of God that transforms our nature in this life.
