Don Carson, commenting on Jesus praying in Gethsemane in Matthew 26:42-44...
In the first garden "Not your will but mine" changed Paradise to desert and brought man from Eden to Gethsemane. Now "Not my will but yours" brings anguish to the man who prays it but transforms the desert into the kingdom and brings man from Gethsemane to the gates of glory.
