2Consider it pure joy, my brothers, whenever you face trials [temptations] of many kinds, 3because you know the testing of your faith develops perseverance.
4Perseverance must finish its work so that you may be mature and complete, not lacking anything. (NIV)
2My brethren, count it all joy when ye fall into divers temptations; 3Knowing this, that the trying of your faith worketh patience.
4But let patience have her perfect work that ye may be perfect and entire, wanting nothing. (KJV)
2Count it all joy, my brothers, when you meet trials of various kinds, 3for you know that the testing of your faith produces steadfastness.
4And let steadfastness have its full effect, that you may be perfect and complete, lacking in nothing. (ESV)
