What do we need to be to grow in Christ?
Another name for flexibility is humbleness.
If a person is bitter, rigid, religious, stiff, that person is in need of humbleness and flexibility.
If we don't have flexibility we are going to have a rough time with following God.
For God is creative and works so outside the box -- He never works in the way we think He will.
The only way we can be content in Him and be free enough to let Him work in our lives is to stay flexible.
If you need flexibility, ask God for help.
