All Christians have faith in God, but the gift of faith that Paul refers to in 1 Corinthians 12:9 is not the same. Jesus often observed that people didn't have enough faith.
For example, when Peter got out of the boat and started to walk on water to Jesus, he started to sink and Jesus said, You of little faith, why did you doubt? (Matthew 14:31).
Jesus also commented that some people had great faith. For example, when Jesus healed a woman's demon possessed daughter he said, Woman, you have great faith! You will get what you asked for (Matthew 15:28).
Hebrews 11 is a whole book about faith. Verse 1 says, Faith makes us sure of what we hope for and gives us proof of what we cannot see. Faith is believing that God knows what he's doing and trusting in him.
The rest of Hebrews lists what we call the Heroes of Faith:
Abel offered a better sacrifice than his brother.
Enoch didn't die, God just took him up to heaven.
Noah built the ark, even though he had probably never seen a flood before.
Abraham moved to a new country.
Sarah had a baby even though she was really old.
All of these people had great faith. They obeyed God because of it.
I believe the gift of faith enables people to look past their circumstances and obstacles, to trust God completely, and do hard things. They know that God is with them and helps them.
