This surely is a good question. We are all anxious to be saved and we are very anxious about the salvation of our families.
It is interesting to me that Jesus doesn’t directly answer the question, but creates an impression of difficulty. He talks about the narrow door. At first glance this seems like a way of minimising entry into heaven. But this is not so. When I pay my way to go to the football, for example, the gate is very narrow – one at a time through the turnstile. But if I am prepared to pay, there is almost no limit to how many can enter the ground.
And Jesus says that if we claim that we once ate and drank with him, He will not know us. How can I be sure Jesus will recognise me? The best way to put these texts together for me is this. The gate is narrow means there is no limit, but we must enter one at a time! Jesus is the gatekeeper. Jesus must know us to get by the gate. He will know us not by our religion or school or parish. He will know us if ever I was kind to him, i.e., his poor!!!!!
