Spiritual immaturity was a concern for the Apostle Paul because, in his absence, the Corinthian church slid into apostasy. And so, it is equally a concern for Brother Singh, for every work of God is a target to be undermined by the devil. For, if someone preaches "another Jesus" than the one he proclaims, or if you receive a different spirit from the one you received in our assembly or you hear a gospel different from the one you accepted, you will readily submit to it. (See 2 Corinthians 11:4) Shepherds jealously guard their flock because our heavenly Father is a jealous God!
