Patience is either passive, seen in a quiet, free, and courageous suffering those evils which God will please in his providence to order us for our portion; or active, seen in a quiet believing, waiting for, and expectation of what God hath promised. Possess your souls, that is, yourselves; do not decline suffering for my name's sake, but live in the exercise of Christian courage and fortitude until the Lord will please to release you. In this sense James expounds this prase, James 1:4, But let patience have her perfect work, that ye may be perfect and entire, wanting nothing. Others say, possess your souls is the same with save your souls. So it seems to be expounded by Matthew 24:13, and Mark 8:13, But he that shall endure to the end shall be saved.
