But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash. When Jesus had finished saying these things, the crowds were amazed at his teaching, because he taught as one who had authority, and not as their teachers of the law. The book of James is written to bring maturity to our lives through seeking the wisdom of God. James wisdom comes straight from the mouth of the master teacher.
Nothing demonstrates our level of maturity more than the tongue.
It speaks from the deepest depths of our being. What we are, is what we live. Christian life is one of sowing and reaping. Fruit we bear produces seed for the next crop. James says God's wisdom produces blessing.
