Have you ever seen the colors of the wordless book. Gold, Red, Black, White and Green. They all stand for something different. Gold represents heaven. Red represents the blood of Christ. Black represents sin in our life. White represents a clean heart when we ask for forgiveness. Green represent our growth in Christ. Green is the hardest one for us to do. Spiritual maturity is hard because we have to move out of our comfort zones. Each day should be an opportunity to grow more and more. We cannot be stagnant and expect great things.
When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
1 Corinthians 13:11
