Go reflects the Great Commission which we find in Matthew 28:19-20 and elsewhere. It's our own living out of the implications from God's promise to Abram in Genesis 12:1-3 and God's desire to bless all peoples through his spiritual descendants. God has created every one of us for a relationship with him through faith in Jesus Christ, and GO is how we participate in what God is doing to pursue and bless that relationship with others.
Love comes from what Jesus called "The Great Commandment" - to "love the Lord your God with all your heart, soul, mind and strength." Following Jesus is a full-time, whole-life commitment, and we desire to grow in that ourselves.
Live is about living in the new life and freedom that Christ offers, and in community with each other as followers of Jesus.
