That which Christ calls us to do,
he will enable us to accomplish.

This is the message of the Miracle of the feeding of the 5,000.
The only miracle recorded in all 4 Gospels, this seems to be the message for the disciples: when Christ would leave the earth, they would be empowered to carry on his message.  And the ability of them to carry out this ministry would not be of their human strength, it would be the power of God.  The power through His Spirit.

Christ called them to feed the multitudes, “You give them something to eat.” (Matt. 14:16)  And amongst the people, five loaves of bread and two fish were found.

Jesus prays a prayer of thanks, breaks the bread, and from this, the food just kept coming.  More and more.  More than they needed.

And the disciples did the work to distribute the food to the people.  “They all ate and were satisfied.”  And “the number of those who ate was about five thousand men, besides women and children.” (Matt. 14:20-21).

Jesus commanded the disciples to feed the people, and through him, they were able to accomplish what he called them to do.

The same is true for us today: That which Christ calls us to do, he will enable us to accomplish.
