I know of three Scriptural ways to become humble. The first is given in Luke 14: do not seek high positions for yourself at church. Seek low positions, and then trust God to elevate you if it is His will.
One meagachurch has successfully started over a dozen other churches. A group of men were cleaning up after the morning service in one of them when a stranger walked in. He enthusiastically told them that he liked what they were doing, and he wanted to be a part of it. They agreed. Then he explained that he wanted to be a leader. The assistant pastor agreed, and told him to get a vacuum cleaner out of a closet and to start on the main auditorium. Afterwards, they would need his help cleaning the rest rooms.
Surprised, the man explained that God had called him to take a leadership position in their church. The assistant pastor then explained that if that were true, then God had called him to start working as a servant, because that's where their leaders came from. The man refused, and the church grew and succeeded without him.
Did God call him to be a leader there? If He did, then the man failed; he didn't follow the teachings of Luke 14. And if God has called you to be a leader, He has called you to seek positions of service as well.
