Mark 8:23 “ ‘If you can’?” said Jesus. “Everything is possible for one who believes.”
Christ turned the question back on the people. They were questioning His power, they were putting an “if” into the equation… so Christ was putting an “if” into their faith.
We need to be sure of our belief in Christ (I hope we all are) and with that depend on Christ to show His might and power to us.
We should not be saying, if you can, but simply be asking “please” and expecting a response.
Jesus has already promised many things to which we need to trust and believe He will do, without the “ifs” and “buts”…
