Jesus was straightforward with his mission when he left. And he gave us the Spirit to accomplish it. He didn’t mince words; he didn’t hide it in the book of Numbers (knowing most of us wouldn’t dare read that). He was and is clear on our mission: Go therefore and make disciples of all nations.
If it is that clear, why do we ignore Jesus and pursue other things so far down the list of “to-dos”?
Bottom line: we don’t know how to make a disciple and/or we ignore how Jesus made disciples.
Jesus continually concentrated on his relationship with Dad (which informed his identity as God’s Son), which then informed his relationships with his disciples and the world.
When we focus on our identity in Christ (the “Up” relationship), the “In” and “Out” will be informed and formed by the gospel . . . the good news. If our “In” and “Out” relationships are informed by our “Up” relationship then discipleship will flow out of that.
