Throughout the years, faithful saints have been willing to lay down their lives for the truth. In Acts chapter 7, we read the account of Stephen’s final message to the nation of Israel. His message infuriated the people so much that they ran upon him and threw stones at him until they crushed the life out of his body. Stephen was martyred because he cared more for the truth's propagation than even his own life and welfare. Though most Christians are not living amongst such severe persecution, our willingness to contend should remain just as fervent. We should pray that God would give us some modern believers who, like Paul, would say, “that in nothing I shall be ashamed, but that with all boldness, as always, so now also Christ shall be magnified in my body, whether it be by life, or by death” (Philippians 1:20)!
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.
