You can't make yourself saved. This is very threatening to people, even Christians, because of what it seems to say about freedom.
John PiperThe further you go in the revealed thoughts of God, the clearer you see that God's aim in creating the world was to display the value of his own glory.
John PiperMarriage is not mainly about prospering economically; it is mainly about displaying the covenant-keepin g love between Christ and his church. Knowing Christ is more important than making a living. Treasuring Christ is more important than bearing children. Being united to Christ by faith is a greater source of marital success than perfect sex and double-income prosperity.
John Piper
