James 1:4 in the King James Version
But let patience have her perfect work, that ye may be perfect and entire, wanting nothing.
Context
3 knowing that the testing of your faith produces endurance.
4 Let endurance have its perfect work, that you may be perfect and complete, lacking in nothing.
5 But if any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him.
