If a believer lives a life to the glory of God, there will come a time when the world wants to know “a reason of the hope” that lies within him. Simon Peter addressed this within the context of times of persecution. When believers were known to “suffer for righteousness’ sake” (1 Peter 3:14), the world would want to question their hope. Simon Peter reminded them of the importance of knowing how to answer their persecutors. Likewise, believers should know how to answer those curious about the gospel of the Lord Jesus Christ. How shameful is it for believers who do not even know how to explain the need for and plan of salvation?
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.
