What an obvious statement, yet people often disregard it, especially when promotion comes. The big head sometimes creeps in when we start thinking we did it all ourselves. You know what that's called, right? It's called pride. And pride is a limited emotion. It normally ends up hitting a brick wall and breaking fast. Thus, little do some realize, promotion comes from one person. The Lord. Period. End of story, which means that God puts decisions on man's heart to act as the go-between to promote or elevate someone. God makes that happen. Not any man (or woman).
The moral of the story is that we better acknowledge who it is who really promotes and elevates us and thank Him every chance we get. That way, when we are sure to give Him the glory, our promotion, our elevation will stay in tact.
Humility over pride wins out all the time. That's how we stay on top.
