"I hope you realize that now is the time to come to Jesus." Meaning that if the aircrew being court-martialed spilled their guts off the record before the proceeding started, they might stand a better chance of a favorable opinion. Could somewhat be compared to plea bargaining.
Also could be something said in the bed, if ya know what I mean ...
2. Oh, baby, come to Jesus, COME TO JESUS!
I'm going to have a "come to jesus" with that kid about his drinking and partying.
