Receive the Spirit
And see, I am sending upon you what my Father promised, so stay here in the city until you have been clothed with power from on high.
Luke 24:49
The risen Jesus' final command in Luke: stay in the city until you are clothed with power from on high. He had already promised the Advocate, the Holy Spirit, who would teach them everything and remind them of all he said.
Jesus commanded them to wait before he commanded them to go. The mission was not to be attempted on willpower. The Christian life runs on received power, the Comforter within, and receiving requires the one posture achievers hate: stopping until you are given what you cannot generate.
Before your next big obedience, wait on purpose. Ask the Father for the Spirit, which Jesus promised he loves to give, and do not substitute hustle for power.
