Jesus said that in the day of judgment, "Many will say to me" that they are His children only to hear the awful words, "I never knew you: depart from me" (Matthew 7:22-23). I don’t want that to happen to anyone, so I never assume that anyone—even if he has had exposure to the gospel—has made the personal choice to believe in Christ as his personal Savior. “But to all who did receive him, who believed in his name, He gave the right to become children of God” - John 1:12
