The document discusses pressing on spiritually towards the goals and calling that God has set. It makes three key points:
1. None of us have fully attained our spiritual goals, so we must continue pressing onwards to what God has called us to.
2. The prize we press towards is the upward call of God. Our focus and citizenship should be on heavenly, not earthly, things.
3. True spiritual growth comes through training ourselves in godliness, such as through spiritual disciplines, not just trying harder. We should gauge growth by love for God and people, not superficial measures.
