Main Points:
A. Acknowledge him & his goodness & plan for us (V.3) including a place in his Kingdom.
B. Believe in him! Make God your refuge and reward (V.4-5). Stand alone if need be. V.4 comes before V. 7.
C. Anticipate spiritual blessing (V.7). Timothy, David, you and I are all people being prepared for a purpose.
D. Engage in your local church structure in faith (2 Ti 1:6, 11, etc.). Evangelize!
