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.
Though peace may seem illusive, God instructs all believers to pursue after it. True inner peace is not something that one can afford to live without. The Bible says, “seek peace, and pursue it.” Peter reiterates this truth by saying, “seek peace, and ensue it” (1 Peter 3:11). Men should seek after peace; and when found, they should allow nothing to prevent them from fully seizing upon it. The Lord said, “therefore love the truth and peace” (Zechariah 8:19). Several New Testament verses repeat the importance of peace by admonishing the believer to follow after it (Romans 14:19; 2 Timothy 2:22; Hebrews 12:14). God certainly wants us to seek peace (1 Corinthians 7:15) and makes peace attainable. Yet, He demands that we pursue after His peace His way because any other peace is really no peace at all.
