God often allows problems to enter people’s lives in order to facilitate His initial plans. For example, God had already expressed His desire to Abram for him to separate from his kindred. For various reasons, Abram had not obeyed God up until this point. In order to bring about God’s desired will, He allowed conflict to enter between the herdmen of Abram and those of Lot. The solution to this unnecessary conflict was quite simple. Abram suggested that they part ways (God’s initial plan) and Abram turned toward the land of Canaan (God’s initial plan). The Lord used the same tactic in the early church to get them to spread out and to preach His word outside of Jerusalem (see Acts 1:8 and Acts 8:1).
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.
