This article teaches on the demands of discipleship: learning, loving, and living. Christ communicates with the disciple and the disciple experiences communion with Christ. The rest of the article discusses in detail these aspects of discipleship.

Only Christians can obey Matthew 22:36-40, because Christians are the only people who are given a heart of flesh which is capable of loving God. This love for God serves as motive for obedience toward God.

One mark of the Christian life is loving God's people. Pietism has an emphasis on personal devotion, and its claim that there is no true church undermines this mark of being a Christian.
