Matthew 28:19-20, “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you;” (that is, the Gospel).
Mark 16:15, “And He said to them, “Go into all the world and preach the gospel to every creature.” (Bold emphasis added for clarity).
Colossians 1:21-23, “And you, who once were alienated and enemies in your mind by wicked works, yet now He has reconciled in the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight–if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven…” (Bold emphasis added for clarity).
Just some “Food for Thought,” but we should remember that we have been called to preach to those outside the spiritual “Church” the Gospel of Christ Jesus, a message of hope and redemption to all whose minds are slaves to the “god of this world!”
Once the Gospel has been received, then it is time to teach the spiritually young how to walk! As I said, just something to think about!
