James 1:4-6 (New International Version)

⁴Perseverance must finish its work so that you may be mature and complete, not lacking anything. ⁵If any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him. ⁶But 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.
