If relationship is the design, then what is the driver? God also provides this for us in the form of a command to love. In fact, it is the Greatest Commandment. Jesus states it like this in Matthew 22:37-40 (ESV):
You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets.
Love is not just a good idea it is a godly command. And this love is not frivolous or conditional. It is a love that is full of goodwill toward self and exhibits the same to others. As Paul defines in 1 Cor. 13:4-8:
Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing but rejoices with truth. Love bears all things, believes all things, hopes all things, endures all things. Love never ends.
This love engages the whole person. We love in thought, emotion and action to walk united in purpose, to live on mission in all areas of life. Remember, if the mission is reconciliation with God, love is a powerful influence toward that directive. Loving people where they are at in their life journey, introducing them to the God who is love (see 1 John 4:8), and walking with them toward fully embracing this love is missional living.
