Man is not saved by works; however, through the new birth, he is “created in Christ Jesus unto” (Ephesians 2:10) and should be “zealous of” (Titus 2:14) good works. The Lord could easily save a man and immediately take him to heaven, but He chooses to leave man here on this earth to do a work for Him. Though the Lord’s work on this earth is made up of many details, it always includes “the ministry of reconciliation” (2 Corinthians 5:18). Similar to the responsibility to tell others about a known cure for a dreaded disease, every Christian has the responsibility to express to others their knowledge of the cure for the coming judgment of God and how to be reconciled to God.
Purity often involves a process. The twofold purification process in the believer's life commences at the moment of salvation. This process then progresses as the believer walks with the Lord. The individual's faith in the finished work of Christ washes away one's sin in Christ’s blood. Christ's blood cleanses completely and purifies every believer from his sin. This cleansing and purification remains forever settled between the Lord and the believer. The born-again Christian will never and can never again be any less pure in his position with the Lord. Peter confirms the positional purity when he wrote that his audience had “purified” (past tense) their souls (1 Peter 1:22). Our purity in position, settled by trusting Christ as Saviour (Titus 2:14), cannot be reversed. However, positional purity does not guarantee purity on a daily basis during our walk. The Christian's practice (his walk) must by choice remain pure.
