2 Chronicles 20:15 — And he said, Hearken ye, all Judah, and ye inhabitants of Jerusalem, and thou king Jehoshaphat, 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.

I have a tendency to worry about whether I can succeed at tasks I have undertaken. I am, of course, mistaken. I’m not always wrong about whether I can or can’t succeed. Where I go wrong is in assuming that it all depends on me. The truth is, of course, that if I’m doing the right things, God is in charge. It’s His battle!
When I realized my mistake I started to think about what that really meant. It’s not just about the Lord picking up His sword and sweeping the enemy aside. In fact I summed it up in five “P’s”. “Planning, Provision, Preparation, Performance and Product”.
Jesus told the apostles, “It is not for you to know the times or the seasons, which the Father hath put in his own power.” (Acts 1:7 KJVA). It is not possible to read through the Bible without realizing that events happen as and when God says. We can’t speed them up, or slow them down to suit our desires! God is in charge of the planning.
Christians often say “When God calls, He provides”. It’s a restatement of Hebrews 13:21. There are plenty more scriptures like 2 Corinthians 9:8 which says ” And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work. God is in charge of Provision.
God will always make sure we are ready for any task He lays upon us. My supporting text is very familiar: “For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.” (Ephesians 2:10 KJVA). We can rely on God’s preparation.
When it comes to performance, “the battle is the Lord’s”. Even when He is working through me, it’s not me — but the Lord — making things happen. Now that doesn’t mean I can be lazy. Myra gave me a clock that sits on my desk at work, and on it is Colossians 3:23, “and whatsoever ye do, do it heartily, as to the Lord, and not unto men;”. For all that though, the performance is God’s.
Sometimes when things don’t work out I can get down, and blame myself. Thinking about it though, if the planning, preparation, provision and performance are the Lord’s, then so is the product. The product is the Lord’s.
The battle is the Lord’s. All aspects of the battle. If you’re like me, and inclined to worry, let it go.
