The church will preach Jesus Christ and Him crucified. She will baptize people into His death. She will distribute His body and blood. She will forgive and retain sins in His name. She will teach her members into full maturity in Jesus Christ.
Children are self-oriented.
They think that they are the center of the universe and that everything exists to meet their needs and personal happiness. As they grow up, they come to see that they are not the center. But in your thinking, in your mind, be grown-ups, adults who have grown up into the fullness of Jesus Christ. Christ gives gifts to his Church. He loves His Church, the way a bridegroom loves His Bride.
