Christian discipleship, true mission, flows out of loving God and loving others.As disciples, our relationships are grounded in the commandments of God.
As God set Israel free from slavery, He wanted to frame their public and private lives by introducing how relationship with Him and with others was to look – you will only have one God, you will not have idols, you will not take His name in vain…. You will not murder, steal, commit adultery, covet your neighbors stuff…
And as Israel would obey these commands in their (to use the words of Newbigin) public and private lives, they would be a light for the nations. And so the Ten Commandments reflect the missional heart of God in the Old Testament (Wright). In the New Testament we find a conversation between Jesus and a well intended young leader. Read Matthew 19:16-26.

Here was a wealthy young man that knew the commands, even kept the commands, but did not possess righteousness that would see him inherit the kingdom of God.
The rich young ruler wanted to know how he could be assured of entering Messiah’s kingdom. What work could he do that would declare him righteous and therefore qualify him for the kingdom?
Jesus’ response was that true Christian discipleship, the commandments, and mission is not centered on our ticking off some list of laws or requirements, but rather grounded in our relationship with Jesus Christ: ²¹ Jesus said to him, “If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me.”
Jesus says in this passage “This is how you will live, do relationships, live in community, worship, be my people, be a witness to the nations…”
go,
sell what you possess and
give to the poor, and you will have treasure in heaven;
and come, follow me.
