“According as his divine power has given to us all things that pertain to life and godliness, through the knowledge of him that has called us to glory and virtue.” 2 Peter 1:3.
In the Christian warfare life, spiritual life, courage, constancy, and decision are needed. Be strong in the Lord. Human courage will not suffice. The Christian soldier must be strong in the Lord. God is all-sufficient. In the omnipotence of His might gird on the armor. Make use of all the proper means of defense against the enemy of souls. You are everyone to perfect an individual character for yourselves. Resist temptation. Cultivate the Christian virtues. Be strong; yea, be strong!
Those who have so many battles to fight must be strong for service. Gain strength and help from the Source of all power. If we trust in the Lord, we shall triumph in the warfare against unseen foes, but if we trust in our own strength, we shall surely meet with defeat. The armor is prepared. Put it on, and fight bravely for the Lord. –The Upward Look, p.129.
The spirit of unselfish labor for others gives depth, stability, and Christlike loveliness to the character, and brings peace and happiness to its possessor. The aspirations are elevated. There is no room for sloth or selfishness. Those who thus exercise the Christian graces will grow and will become strong to work for God. They will have clear spiritual perceptions, a steady, growing faith, and an increased power in prayer. The Spirit of God, moving upon their spirit, calls forth the sacred harmonies of the soul in answer to the divine touch. Those who thus devote themselves to unselfish effort for the good of others are most surely working out their own salvation. –Steps to Christ, p. 80.
