Acts 24:15-16 – And have confidence in God that there is about to be the resurrection of the dead, both of the righteous and the unrighteous, which they themselves also await. Because of this, then, I continually exercise myself to have a blameless conscience before God and man.
Paul was committed to being pure and blameless on the day of the resurrection (Philippians 1:9-11). To this end, he would not allow his heart to condemn him. He saw the blood of Jesus as the means to purify his conscience. Therefore, Paul took a similar position to Job who said, “My righteousness I hold fast and will not let it go; my heart will not reproach me so long as I live” (Job 27:6).
Paul takes the state of the conscience and places it at center stage with faith when he commanded us to hold on to faith and a good conscience in our walk with the Lord Jesus Christ (1 Timothy 1:19). A pure conscience is a state of the heart that does not allow any accusation against our relationship with God. The blood of Jesus purged our conscience so we can serve God without any sense of sin (Hebrews 9:14, 10:22; 1 John 3:21). The work of grace has brought us into the faith that confesses we are in Christ Jesus; and therefore, there is no condemnation or guilty conscience (Romans 8:1; 2 Corinthians 5:17,21).
