English Standard Version (ESV)
What drives you? What is the one thing you would do if you could only do one thing? What moves you?
Here, Jesus is trying to tell the disciples about his relationship with his father. The love is so deep that it is as food for Jesus. He needs it to nourish him. Jesus sees the mission of God before him, reaching the lost, and he is focused on this. He is connected to the Father.
We are always grasping for this connection, to learn how to love the Father, how to let that relationship be the defining one in our lives, to live in the center of God's will and be led by the Spirit. We strive to be driven primarily by God's will.
I take comfort in knowing the disciples had a hard time with it. It didn't come easily or naturally to them -- they had many questions for Jesus. So we join their struggle, trying to understand how Jesus is calling us to live, striving to put God first, day by day.
