John came preaching repentance, calling for people to change their ways in order to be ready for the messiah.  He warned the religious leaders not to trust in their own righteousness, but to seek God.  He says that God will soon fulfill the promises in scripture.  Paul also calls Christians to look to scripture to provide encouragement and endurance as well as hope, joy and peace.

God provides scripture to give us all we need for a life of faith in Christ.
