We will have "bridled"-or learned to keep in check-our entire body. Once we learn to perfectly control our words, we will be in perfect control of every part of ourselves. They will only and ever say words motivated by faith in God and love for each other. Such a perfected believer will never say anything unkind, hurtful, selfish, proud, rude, or manipulative. The sign of a Christian who has arrived at full-faith perfection is one who never stumbles in what they say or how they say it. We're not there yet, especially when it comes to our words. However, James also reveals that our goal is to stop stumbling, to be in full control of ourselves at all times. One struggle of the Christian life is our awareness of the many ways we continue to stumble.
And yet, James is fully aware that fallible human beings will never do so without stumbling.
G enuine Christians will participate in genuine good works in obedience to God. It is clear - we all stumble in many ways.
