Remind the children that Christians gather together to help one another live God’s way. Christians help each other by (1) doing things together and (2) through fellowship.
Ask the children to think for a moment what it would be like if Christians who met together didn’t get along with one another. Now ask them to think what it would be like if Christians who gathered together loved each other with ‘agape’ love, putting each other first and expecting nothing in return.
Christians believe it is important that they love one another so that together they can do things well, and so that the Holy Spirit can work powerfully among them as they fellowship with one another.
In Bible times the Apostle Paul asked God to help the Christians live in unity, to live in such a way that they get on together. Today Christians believe they can ask God to help them live in unity too so that even when there are differences among them they get on together.
