It is always a painful experience to see those who once walked with the Lord now walking contrary to Him. Families and friends are hurt because of those now living contrary to God’s dictates. Paul warned Timothy that this departure from the faith would take place in the last days. A firm and consistent stand for the faith would give way to an increase in the influence of seducing spirits and doctrines of devils. No doubt, this has occurred since the inception of the New Testament church, but Paul warned that it would increase to its apex in the latter times. In response to the coming danger, Paul admonished the young preacher to be “nourished up in the words of faith and of good doctrine” (1 Timothy 4:6). This shows that the best defense against departing from the truth is a consistent feasting upon the truth.
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.
