John 6:26-27 WEB
Jesus answered them, “Most certainly I tell you, you seek me, not because you saw signs, but because you ate of the loaves, and were filled.  Don’t work for the food which perishes, but for the food which remains to eternal life, which the Son of Man will give to you. For God the Father has sealed him.”
How can we tell when God has sealed, or approved, someone for a task? How did God seal Jesus? God sealed Jesus through the testimony of John the Baptist and the miraculous signs which Jesus did. Signs and wonders accompanied Jesus. God used miracles as signs of Jesus’ task and calling.
Jesus was also blessed. He had decent clothes, or at the crucifixion, the soldiers would not have struggled to get his clothes. They were nice. Also, Jesus was from Nazareth, but he seems to have a house in Capernaum. Jesus stopped working when he went into ministry, how did he pay for these things? Jesus may have saved some money while he worked, but that would contradict part of his message. It seems likely people were supporting his ministry.
So, God used signs and wonders and ministry support to show approval, but there is another sign. The preaching of repentance also accompanies the one whom God approves. Both John the Baptist and Jesus preached repentance. Another, Paul the apostle, was always encouraging believers to turn from sin. Many of the biblical writers wrote about sin and repentance. Preaching repentance is a mark of the one sealed by God.
Lord Jesus, help me recognize and honor the ones you have sealed. Give me a discerning Spirit so I can recognize when you have set your approval on another. In Jesus’ name, I pray, amen.
