I know this may seem short but this truth has given me great joy. There are times in our lives where we devalue ourselves, and even devalue others. We will never live up to the calling of Christ on our own, and Satan wants hit you hard with this truth and close your eyes to Christ. Know that it is Christ who makes you worthy of his calling by his blood. Also know that your identity is at the cross, and at the cross there is Jesus who makes you perfect. Set your identity in Jesus and you will be made worthy, not by your works but his finished work on the cross.
