I seem to be spending a bit of time in the Book of James lately.
James 1:5-8 states:
'If any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him.
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.'
My Life-Application Study Bible provides lots of insight and clarification on this:
'By wisdom, James is talking not only about knowledge, but about the ability to make wise decisions in difficult circumstances. Whenever we need wisdom, we can pray to God, and He will generously supply what we need. Christians don't have to grope around in the dark, hoping to stumble upon answers. We can ask for God's wisdom to guide our choices.
Wisdom means practical discernment. It begins with respect for God, leads to right living, and results in increased ability to tell right from wrong. God is willing to give us His wisdom, but we will be unable to receive it if our goals are self-centered instead of God-centered. To learn God's will, we need to read His Word and ask Him to show us how to obey it. Then we must do what He tells us.
To "believe and not doubt" means not only believing in the existence of God, but also believing in His loving care. It includes relying on God and expecting that He will hear and answer when we pray.
A mind that wavers is not completely convinced that God's way is best. It treats God's Word like any human advice, and it retains the option to disobey. It vacillates between allegiance to subjective feelings, the world's ideas, and God's commands. If your faith is new, weak, or struggling, remember that you can trust God. Then be loyal to Him. To stabilize your wavering or doubtful mind, commit yourself wholeheartedly to God.
Doubt leaves a person as unsettled as the restless waves. If you want to stop being tossed about, rely on God to show you what is best for you. Then your decisions will be sure and solid.'
Winners know the source of, and plug in to, true wisdom.
