"If grace has really changed our hearts, we don't ultimately care if life goes the way we want it, as long as we have him. The joys of acclaim, wealth, and power are nothing compared to the eternal acclaim, wealth, and power we have in him... Internally, this quiets the soul into profound contentment and poise. Externally, it means humility, a willingness to learn from others and also to trust God...A Christian should never have the attitude toward God, "what have you done for me lately?""
