"Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber. But he that entereth in by the door is the shepherd of the sheep. To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out."
John 10:1-3
Sometime ago I was at the airport getting ready for a flight when I saw an actor. I remembered having seen him on television reruns in Korea when I was a boy, so I introduced myself and began to talk to him. As he was very friendly and open to talking, I asked about some of his acting work and then took the opportunity to witness to him. As I shared the Gospel with him, he told me he had played a big role in a Christian film back in the 1970s and that he "knew about that stuff."
I hope that he truly is converted, but it is certain that being in a Christian film, going to church, getting baptized, being confirmed, or anything else that we do or don’t do will not save us. Salvation through faith in Jesus Christ is the only way to Heaven. Our world pushes the idea of all religions being different yet viable paths to the truth; the premise is that any kind of faith will be pleasing to God.
Those of us who know the truth have a great responsibility to stand against that false idea and explain clearly that Jesus is God’s only plan of salvation. 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 knows that he must trust Christ in order to enjoy salvation.
