We definitely get into trouble when we overthink something, try to reason it out in our own understanding, or fall into unbelief. Vacillate means to weigh something back and forth in our mind. James 1:8 says, “He is a double-minded man, unstable in all his ways.”
As we grow in our maturity, we set old patterns aside. 1 Corinthians 13:11 says, “When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things.”
I remember in kindergarten that they endeavored to teach us to share. In first grade we had a workbook called “Me First.” Philippians 2:3-4 is a template of maturity. It says to let nothing be done through selfish motives, “…but in lowliness of mind let each esteem others better than himself.” As we mature in our walk with the Lord, we will represent Him more than selfish selves.
