Beware how you neglect secret prayer and a study of God's word. These are your weapons against him who is striving to hinder your progress heavenward. The first neglect of prayer and Bible study makes easier the second neglect. The first resistance to the Spirit's pleading prepares the way for the second resistance. Thus the heart is hardened, and the conscience seared.
On the other hand, every resistance of temptation makes resistance more easy. Every denial of self makes self-denial easier. Every victory gained prepares the way for a fresh victory. Each resistance of temptation, each self-denial, each triumph over sin, is a seed sown unto eternal life. Every unselfish action gives new strength to spirituality. No one can try to be like Christ without growing more noble and more true.
