“For in many things we offend all. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.”
James 3:2

Notice he said, the words spoken would eventually influence the life of a man. What precious truth! This means if we speak only the word of God, our lives would become solely the expression of the word of God, it means we would become an expression of all that matters to God, Jesus had said, only the word of God is needful: Luke 10:38-42
So before you make that statement- ponder, who did you hear it from? If God gives you words to influence your life, then the world and its god, satan, gives their words, statements, teachings and connotations to influence your life unto destruction.
“The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.” John‬ ‭10‬:‭10‬ ‭KJV‬‬
Your life can be so beautifully matched as Jesus; and you can get a point were just like Jesus you can boldly say:
“I speak that which I have seen with my Father…” John‬ ‭8‬:‭38‬
