We may say many things that sound true but in reality are not. Simply because some speech contains verified fact and precise data does not constitute its truth, especially in regard to the Word of God. The greatest thing about God is found in 1 John 4:8, "God is love." Every thing He speaks is spoken within His own character. Love is not an emotion; love is a Person. Neither is truth an understanding; it is a Person. When that which I speak ceases to convey the personality of God, Who is love, then what I say ceases to be truth.
How quick we are to stand up for truth when we are challenged. More often than not our stand is upon insecurity and self-defense rather than truth. Jesus Christ stood for truth when He allowed the angry mob to crucify Him and spoke forth the character of His own life, "Father forgive them, for they know not what they do." Christians are too quick to be at one another over points of doctrine. Even if they could prove they were right, they would be wrong for their lack of love. There is no truth apart from the character and essence of God, and God is love.
In Ephesians 4:14-15, Paul gives us instruction to cause us to avoid deception. That is, "Be no more children." Spiritual children make issues whereby many are hindered and confused. Spiritual adults are "grown up into Him in all things, which is the head, even Christ."
