Mark 12
30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
31 And the second is like, namely this, Thou shalt love thy neighbour /family as thyself. There is none other commandment greater than these.
Your first love must be Jesus Christ and as he is the head of the church that is what you are doing as you give your time, talents and everything the Lord has give you. One of the things the Lord has given you is your family, your closest neighbors. The children God gives you are his children by serving them you are serving God. It's all part of one and the same thing!
