God uses chronic pain and weakness, along with other afflictions, as his chisel for sculpting our lives. Felt weakness deepens dependence on Christ for strength each day. The weaker we feel, the harder we lean. And the harder we lean, the stronger we grow spiritually, even while our bodies waste away. To live with your โthornโ uncomplainingly โ that is, sweet, patient, and free in heart to love and help others, even though every day you feel weak โ is true sanctification. It is true healing for the spirit. It is a supreme victory of grace.
J. I. PackerBut man's eyes are blind through sin, and he can discern no part of God's truth till the Spirit opens them. Inner illumination, leading directly as it does to a deep, inescapable conviction, is thus fundamental to the Spirit's work as a teacher.
J. I. PackerNothing can alter the character of God. In the course of a human life, tastes and outlook and temper may change radically: a kind, equable man may turn bitter and crotchety: a man of good-will may grow cynical and callous. But nothing of this sort happens to the Creator. He never becomes less truthful, or merciful, or just, or good, than He used to be.
