We begin by trusting our ignorance and calling it innocence, by trusting our innocence and calling it purity. When we hear Jesus declare that “out of the heart come evil thoughts,” we shrink and say, “But I never felt any of those awful things in my heart.” We resent what Jesus Christ reveals.

Either Jesus Christ is the supreme authority on the human heart, or he isn’t worth paying any attention to. Am I prepared to trust his diagnosis? If instead I choose to trust my innocence, eventually I will come to a place where, with a shuddering awakening, I discover that what Jesus Christ says is true. Then I’ll be appalled at the potential for evil and wrong inside me. As long as I remain under the refuge of innocence, I’m living in a fool’s paradise. If I’ve never been a cheat or a menace, the reason is a mixture of cowardice and the pressures of human society. When I am undressed before God, I find that Jesus Christ is right in his diagnosis.

The only thing that safeguards the human heart is the redemption of Jesus Christ. If I will hand myself over to him, I never need to experience the terrible possibilities that lie within my heart. Purity is too deep down for me to get to on my own, but when God comes in, he brings into the center of my personal life the very same Spirit who was manifested in the life of my Lord: the Holy Spirit. From then on, the spotless purity of Jesus Christ is mine.

Psalms 40-42; Acts 27:1-26

Wisdom from Oswald

There is nothing, naturally speaking, that makes us lose heart quicker than decay—the decay of bodily beauty, of natural life, of friendship, of associations, all these things make a man lose heart; but Paul says when we are trusting in Jesus Christ these things do not find us discouraged, light comes through them.
