As explained in his autobiography Surprised by Joy, C. S. Lewis was not the happiest of all converts. Later, though, he realized a deep truth about the character of God through his conversion experience:
In the Trinity Term of 1929 I gave in, and admitted that God was God, and knelt and prayed; perhaps, that night, the most dejected and reluctant convert in all England. I did not then see what is now the most shining and obvious thing; the Divine humility which will accept a convert even on such terms.
The Prodigal Son at least walked home on his own feet. But who can duly adore that Love which will open the high gates to a prodigal who is brought in kicking, struggling, resentful, and darting his eyes in every direction for a chance of escape?
The words . . . compel them to come in, have been so abused by wicked men that we shudder at them; but, properly understood, they plumb the depth of the Divine mercy. The hardness of God is kinder than the softness of men, and His compulsion is our liberation.
