The pursuit of joy in God is not optional. 
 It is not an \'extra\' that a person might grow into after he comes to 
 faith. Until your heart has hit upon this pursuit your \'faith\' cannot 
 please God. It is not savng faith. Saving faith is the heartfelt 
 conviction not only that Christ is reliable, but also that He is 
 desirable.

My mother, who grew up in Pennsylvania, literally washed my mouth out with soap once for saying, 'Shut up!' to my sister. She would have washed my mouth out with gasoline if she knew how foul my mouth was racially when she wasn't around.

We look at our circumstances - perhaps persecution or disease or abandonment - and we conclude that we are not loved by Jesus anymore. That’s the opposite of abiding in the love of Jesus.

The 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.
