It isn't sex by itself that makes abortion. It is sex plus covetousness: desiring things that God does not will for us to have because we are not willing to find our satisfaction in him. Illicit sex and unencumbered freedom without children: for these we covet, and abortion is the result.
John PiperThe inner essence of worship is cherishing Christ as gain - indeed as more gain than all that life can offer - family, career, retirement, fame, food, friends. The essence of worship is experiencing Christ as gain. Or to use words that we love to use around here: it is savoring Christ, treasuring Christ, being satisfied with Christ.
John PiperThe highest meaning and the most ultimate purpose of marriage is to put the covenant relationship of Christ and his church on display. That is why marriage exists. If you are married, that is why you are married. If you hope to be, that should be your dream.
John PiperWithout extended, concentrated prayer, the ministry of the Word withers. And when the ministry of the Word declines, faith (Rom. 10:17; Gal. 3:2, 5) and holiness (John 17:17) decline. Activity may continue, but life and power and fruitfulness fade away. Therefore, whatever opposes prayer opposes the whole work of ministry.
John Piper
