Please explain why Jesus found faith within unregenerate people?
The Centurion (gentile) in Matthew 8
10 When Jesus heard it, he marvelled, and said to them that followed, Verily I say unto you, I have not found so great faith, no, not in Israel.
The friends of the man sick with palsy in Matthew 9
2 And, behold, they brought to him a man sick of the palsy, lying on a bed: and Jesus seeing their faith said unto the sick of the palsy; Son, be of good cheer; thy sins be forgiven thee.
The woman who touched Jesus' garment and was healed in Matthew 9
22 But Jesus turned him about, and when he saw her, he said, Daughter, be of good comfort; thy faith hath made thee whole.
The woman whose daughter was healed of her demon possession in Matthew 15
28 Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour.
I could go on and on. The point being here is God, as Jesus, finding faith in people. Any evidence from the context of the scripture that these people were regenerated and/or given the "gift of faith?" No.
