Believers should seek to be pure in every facet of life. One might consider limiting this to the places he goes or the things he hears and sees, but purity demands a much greater focus. Believers ought to think on pure things (Philippians 4:8) with pure minds (2 Peter 3:1) and pure consciences (1 Timothy 3:9; 2 Timothy 1:3). In particular, believers should have pure hearts before the Lord (1 Timothy 1:5; 2 Timothy 2:22). A pure heart will lead to a pure conscience and a pure mind. A pure heart changes where a man goes, what he looks upon, and the things he allows to enter into his ears. Every Christian should strive to make sure that all things are pure.
“Out of the abundance of the heart the mouth speaketh” (Matthew 12:34). As such, the words that proceed from our mouths provide helpful insights into the condition of our hearts. A man can only deceive with his words for so long; eventually, his speech exposes the reality of his heart's condition. The Bible reinforces this truth when it says, “the words of the pure are pleasant words” (Proverbs 15:26). The Bible also identifies words of praise to God as “pleasant” words (Psalm 135:3; Psalm 147:1). Impure words manifest an unpleasantness. Whereas, a pure heart utters pure words and speaks of the Lord and of His goodness.
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.
