And now I commit you to God and to the message of His grace, which is able to build you up and to give you an inheritance among all who are sanctified.
Paul just warned his friends that wolves were coming.
His confidence in leaving them to fend for themselves in the face of these foretold attacks was twofold:
He was leaving them in the powerful hands of their Father.
Also, he had preached to them the full counsel of God so that they were not without artillery to defend their hearts and minds against falsehood and heresy.
The message of grace genuinely received and believed by a person transfers them from the family of death to the household of life as an adopted child of the eternal King!
Preach this message, share this message and those who believe can be left in confidence that the Good News and the Good King will keep them safe (even in the face of great trial and difficulty!)
