We are all more or less familiar with defending the faith. We have read books on the subject, practiced the techniques we've heard, discussed it, etc. At times we may be "defending the faith" on several fronts at a time; other times we seem to be waiting for the next attack.
Quite regularly I get weary; I don't see that my attempts are doing any good. There seems to be an endless supply of atheists, agnostics, Muslims, new agers, false ideas in otherwise Christians, and so on. An apologist's work is never done.
Then the Spirit of God pipes up and says, "Hearken ye...thus saith the Lord unto you, be not afraid nor dismayed by reason of this great multitude; for the battle is not yours, but God's" (2 Chronicles 20:15). The pressure is off! I can rest. There is a great multitude, but that is God's battle, not mine. Sometimes He even wants me to stay out of His way: "Ye shall not need to fight in this battle;...stand ye still, and see the salvation of the Lord with you...." (20:17)
While I am arguing for an all powerful creator, I'm sometimes forgetting that He can take care of Himself. He that made the world can control it; He that saves my soul can save Himself if He likes. If He lets the wicked abound, He does not ask me to step in and do His job for Him. He does provide me with plenty of opportunities which He certainly wants me to take, but His main goal for me is fellowship with Him.
This is really the best defense of the faith, a group of followers dedicated to God, worshipping Him in Spirit and in truth. Better than all creationist material ever written are living epistles, known and read of all men. In this case, the best defense is no offensiveness.
This is not the case with the world; they have no omnipotent God to take care of them. It is their job to fight for what they believe, yet their belief cannot provide them the rest that God would. They are the servants of their beliefs, and these beliefs are hard masters (Romans 6:16).
Praise God that His yoke is easy, and His burden is light (Matthew 11:30)!
