“I can do all things through Christ which strengtheneth me,” Philippians 4:13.
One of Jesus most outstanding character traits is charity or pure love. In 1 Corinthians 13 we learn that part of this pure love is patience and kindness. We are also taught that all sacrifices, successes, learning, and spirituality are nothing and will do us no good on earth or in heaven if we don't learn how to treat people with charity.
"...walk worthy of the vocation wherewith ye are called, with all lowliness and meekness, with longsuffering, forbearing one another in love; endeavoring to keep the unity of the Spirit in the bond of peace." Ephesians 4:1-3
Patience and kindness are not easy. Yelling and throwing tantrums are, at least at first. However, the former will bring peace. The latter simply makes one appear childish and foolish. When we tell someone how it is in no uncertain terms, we might feel better and even a bit powerful briefly. However, one way or another, our grievous words stir up anger. “A soft answer turneth away wrath: but grievous words stir up anger,” Proverbs 15:1. For sure it isn't the way to inspire others to love us.
For sure patience and kindness are difficult choices. If we know why it is important to choose them, it is easier. If we allow Jesus' grace to touch our hearts, these choices are easier. Yes, it is hard to breathe and choose love, when someone lashes out with unkindness. “Great peace have they which love thy law: and nothing shall offend them,” Psalm 119:165.
"He that is slow to wrath is of great understanding: but he that is hasty of spirit exalteth folly," Proverbs 14:29 Listen first; speak later but only with understanding and charity. "A wrathful man stirreth up strife: but he that is slow to anger appeaseth strife," Proverbs 15:18. In most cases, it isn't important to be right in an argument. A quiet example of patience and kindness will win people over much more quickly. Seriously, who of us is perfect and doesn't make a mistake? Patience and kindness help us see others as works in progress and give the benefit of a doubt. "See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men," Thessalonians 5:15.
So...instead of pointing out the faults of others with disapproving thoughts/words or anger, choose instead peace and stillness. Choose patience and kindness just as you would like others to do for you if the tables were turned. "And he arose, and rebuked the wind, and said unto the sea, Peace, be still. And the wind ceased, and there was a great calm," Mark 4:39
