As a baby Christian?
God answered your every prayer?
Even today.
Does He answer your every prayer?
Jesus said if we have the faith of a mustard seed, if we pray for a mountain to be moved?
That it would be moved.
So, when the mountain was not moved after such a prayer?
You have no faith?
Or?
You were not praying in the Lord's will?
Peter was not infallible.
Now when Peter had come to Antioch, I withstood him to his face, because he was to be blamed;
for before certain men came from James, he would eat with the Gentiles; but when they came, he
withdrew and separated himself, fearing those who were of the circumcision. And the rest of the
Jews also played the hypocrite with him, so that even Barnabas was carried away with their hypocrisy."
Galatians 2:11-13
Peter's errors were recorded for us to see and to learn from.
He was not infallible.
Peter was, for a while, was a sucker for good intentions.
Assuming what he felt, was what God felt.
He spoke this word openly. Then Peter took Him aside and began to rebuke Him.
But when He had turned around and looked at His disciples, He rebuked Peter,
saying, “Get behind Me, Satan! For you are not mindful of the things of God, but
the things of men.”
Mark 8:32-33
Peter did not say God instructed him to find a replacement for Judas.
Peter simply assumed that God felt the same way that he did.
This is how we learn along the way.
