"But when he asks, he must believe and not doubt, because he who doubts is like a wave of the sea, blown and tossed by the wind. That man should not think he will receive anything from the Lord; he is a double-minded man, unstable in all he does." James 1:6-8
I don't know if you have ever played golf but if you have you know it is a hard game. If you haven't you can take my word for it. But I have noticed it is easier when I can fully commit to a shot. My last round I had one of those days where it seemed like every shot was from an awkward lie or an uncomfortable distance so that I was never quite sure whether to go up a club or down a club. So I really struggled to hit those shots with confidence. When there is the slightest bit of doubt as I hit the shot, it seldom turns out well.
Anytime I stand over a shot with uncertainty in my mind the result is seldom good.
In other words, it is hard to play golf when I have conflicting thoughts about the club selection or the correct distance or what sort of shot I should hit from the lie I have. When I am double-minded my game is unstable and results in double bogeys.
However, when I am facing a shot that has a comfortable distance and a good lie and I know exactly what club to hit, then I can commit to the shot and hit it with confidence and the result is much better.
In the same way, life is more difficult when I am uncommitted. Any time there is doubt or confusion or indecision life gets more difficult. When I doubt God or am not fully convinced about His Word or indecisive in regard to His will, life gets harder.
James, in these verses admonishes believers to be fully convinced about God's goodness and His grace and the truth of His Word. When I am committed to God in these ways, my life gets immediately better.
I want to be a single-minded follower of Christ. I don't want to second-guess Him nor live in confusion or doubt. I want to walk with faith and confidence in my Christian life. That is what commitment is. Commitment is being single-minded and fully convinced God is Who He says He is.
When Jesus was facing the temptations from the Devil in the wilderness, what the devil was after was getting Jesus to doubt the goodness and the holiness of God. He wanted to shake the Lord's confidence in His Father and under mind His faith. In short, the Enemy wanted to offer the Lord a "Plan B" in place of the suffering on the cross.
But the Lord would have nothing of it! He countered each time with truth from the Bible. He affirmed truth in the face of deception. He was committed to "Plan A" completely and exclusively. That is what commitment is!
Is commitment hard for you? Are you struggling with double-mindedness? Do you struggle with doubting God and/or yourself?
"A double-minded man is unstable in all his ways!" Stablilize you heart and you spirit and your mind by fully committing to Christ. Commitment is easier when there is just a Plan A!
