We belittle God when we go through the outward motions of worship and take no pleasure in His person.
John PiperThe formation of the life of a person in the womb is the work of God, and it is not merely a mechanical process but a work on the analogy of weaving or knitting: "Thou didst knit me together in my mother's womb" (psalm 139:13). The life of the unborn is the knitting of God, and what He is knitting is a human being in His own image, unlike any other creature in the universe... The destruction of conceived human life - whether embryonic, fetal, or viable - is an assault on the unique person-forming work of God.
John PiperWe give glory to God when we trust him to do what he has promised to do-especially when all human possibilities are exhausted. Faith glorifies God. That is why God planned for faith to be the way we are justified.
John PiperAccording to the spirit of this age, the ultimate sin is no longer the failure to honor and thank God but the failure to esteem oneself. Self-abasement, not God-abasement, is the evil. And the cry of deliverance is not "O wretched man that I am, who will deliver me?" but "O worthy man that I am, would that I could only see it better"!
