1. In God’s family everyone has a contribution to make.

8 For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— 9 not by works, so that no one can boast. 10 For we are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do. Ephesians 2:8-10

4 For just as each of us has one body with many members, and these members do not all have the same function, 5 so in Christ we, though many, form one body, and each member belongs to all the others. 6 We have different gifts, according to the grace given to each of us. If your gift is prophesying, then prophesy in accordance with your faith; 7 if it is serving, then serve; if it is teaching, then teach; 8 if it is to encourage, then give encouragement; if it is giving, then give generously; if it is to lead, do it diligently; if it is to show mercy, do it cheerfully.
Romans 12:4-8

2. In God’s family cooperation makes the impossible possible.

9 Two are better than one, because they have a good return for their labor: 10 If either of them falls down, one can help the other up. But pity anyone who falls and has no one to help them up. 11 Also, if two lie down together, they will keep warm. But how can one keep warm alone? 12 Though one may be overpowered, two can defend themselves. A cord of three strands is not quickly broken. Ecclesiastes 4:9-12

11 So Christ himself gave the apostles, the prophets, the evangelists, the pastors and teachers, 12 to equip his people for works of service, so that the body of Christ may be built up 13 until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ. 14 Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of people in their deceitful scheming. 15 Instead, speaking the truth in love, we will grow to become in every respect the mature body of him who is the head, that is, Christ. 16 From him the whole body, joined and held together by every supporting ligament, grows and builds itself up in love, as each part does its work.
Ephesians 4:11-16
