In the last days, believers must remain alert. There is no time for sleeping. For it is while believers sleep that the enemy works most effectively. Even the Lord Jesus acknowledged the great need of the day when He said, “I must work the works of him that sent me, while it is day: the night cometh, when no man can work” (John 9:4). Just as it was in the days of Gideon (Judges 7:5-7), the Lord wants soldiers who are fully aware of their surroundings. A sober minded believer keeps his eyes open, knowing he has an enemy that is on the prowl and ready to devour (1 Peter 5:8). The sober minded believer also knows that one lapse in judgment can cause immense damage during the spiritual battle. Sobriety keeps every reality in the forefront of the mind.
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.
From the Old Testament to the New Testament, many things change; however, some themes remain constant. One such theme involves the Lord's desire to use pure things and pure people. God commanded His people in the Old Testament to make sure the things used in the tabernacle were purified (Leviticus 8:15). He also commanded that His servants be purified (Ezra 6:20). In the New Testament, the apostle Paul confirmed the continuation of this theme by saying that “pureness” approved him as a minister of God (2 Corinthians 6:4-6). God still requires those who serve to strive to live pure and holy lives. Impurities hinder the Lord’s effectiveness in our lives though we may not be aware of the hindrance.
