For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith. For as we have many members in one body, and all members have not the same office: So we, being many, are one body in Christ, and every one members one of another.
Romans 12:3-5
We live in a society that promotes and glorifies in self. Whether it is self-esteem, self-respect, or the “selfie” picture, we are encouraged to focus our attention and efforts not toward others, but toward ourselves. Yet God's command is not that we focus on ourselves, but on others. This is the pattern Jesus set for us to follow. When the disciples squabbled over who would have the most prominent positions, He told them to focus on others instead, and said, “For even the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many” (Mark 10:45).
Everything in life flows from where our focus is. If it is strictly internal, we will not make the efforts and sacrifices required to do God's work. Instead we will tend to become proud and vain, looking at ourselves as much more than we really are. J. Stuart Holden said: “We sometimes speak of men and women—even Christian men and women—being wrapped up in themselves, and when a man is wrapped up in himself, he makes a very small parcel. When he has shrunk to that size so that he can be wrapped up in himself, there is not much to wrap up.”
It is God's grace that offers us a place in His service. He certainly does not need our help, nor is He impressed with our talents, our fame, or our resources. He blesses those who are not self-focused, but instead live out their love for Him by investing in the lives of others.
