The love God wants

"He said to him the third time, 'Simon, son of Jonah, do you love Me?' Peter was grieved because He said to him the third time, 'do you love Me?'And he said to Him, 'Lord, You know all things; You know that I love You.'Jesus said to him, 'Feed My sheep.'" John 21.17

Why did Jesus ask Peter if he loved Him? From my understanding, he wanted to teach about pure and true love. Just as faith requires attitude, love also requires action. Those who think that pure love is a feeling are completely wrong. It is not. Just as  and faith, it also requires sacrifices.

The sheep

"My sheep hear My voice, and I know them, and they follow Me." John 10.27

What characterizes the relationship between shepherd and sheep is the shepherd's voice. No sheep from a certain flock follows the voice of a shepherd of another flock.
It was common that several shepherds would gather their respective flocks to drink from the same stream. But once their thirst was quenched, each sheep would follow the voice of their respective pastors.
The followers of the Good Shepherd, hear His voice and follow Him. That is, obey.

Sheep of the fold

“ I will surely assemble all of you, O Jacob, I will surely gather the remnant of Israel; I will put them together like sheep of the fold, like a flock in the midst of their pasture; they shall make a loud noise because of so many people. " Micah 2:12

The eyes of the Lord are looking for those who are thirsty of His Spirit. He's calling them to take advantage of the real life He has to offer them. This is the faith of the Fasting of Daniel! Everyone in one spirit, one only faith, unanimous determination for the 17th April, when they'll take possession of the Greatest Promise.
