Telling someone that they should focus on someone other than themself is probably one of the most difficult messages to convey. It leaves the sender feeling sheepish, and the recipient feeling angry, at best. The Lord God Almighty needs everyone to do a self-assessment on this issue, so as to avoid derailing relationships.
Ask the indwelling Holy Spirit Of God whether you have become self focused. Ask him to give you one assignment each day that can enable you to focus on someone other than yourself. Ask him to tell you if and when you no longer need these assignments. Ask him also, to report your progress to the Lord God Almighty. Ask him periodically during the next one thousand years, to ensure that you remain on track.
