Further Thought: Even amid the heavy theology, Peter’s letters put a strong emphasis on Christian life and how we should treat one another. In other words, yes, we need to know the truth as it is in Jesus. But even more important, we need to live the truth, too. Early on, we get these grand words: “Since you have purified your souls in obeying the truth through the Spirit in sincere love of the brethren, love one another fervently with a pure heart” (1 Pet. 1:22, NKJV).
Notice how he links the purifying of our souls with obedience to the truth. The truth changes us, making us into people who love one another fervently and with “a pure heart.” Obedience, purity of heart, and love-all three are related to one another. This is the ideal we should be striving for. Can you imagine how different our lives and our churches would be were we to follow this charge? Think what it would do for the sense of church unity, if nothing else. “Brethren, will you carry the spirit of Christ with you as you return to your homes and churches? Will you put away unbelief and criticism? We are coming to a time when, more than ever before, we shall need to press together, to labor unitedly. In union there is strength. In discord and disunion there is only weakness.” – Ellen G. White, Selected Messages, book 2, pp. 373, 374.
