Jesus went through towns and villages, teaching the people and making His way to Jerusalem. Someone asked Him, “Sir, will just a few people be saved?”
Jesus answered him, “Do your best to go in through the narrow door; because many people will surely try to go in but will not be able. The master of the house will get up and close the door; then when you stand outside and begin to knock on the door and say, ‘Open the door for us Sir!’ He will answer you, ‘I don’t know where you come from! Then you will answer, ‘We ate and drank with you; you taught in our town! But He will say again, ‘I don’t know where you come from. Get away from me you wicked people!’ How you will cry and gnash your teeth when you see Abraham, Isaac and Jacob, and all the prophets in the kingdom of God, while you are thrown out! People will come from the east and the west, from the north and the south, and sit down at the feast of God. Then those who are now last will be first, and those who are now first will be last.” Luke 13: 22-30
In not so many words, this verse emphasizes that not everyone who calls themselves a believer will enter the kingdom of God.
Faith is like a two-sided coin. One side of faith is where one sings, praises God, attends mass/service and tithes… And the second side of faith is doing works of mercy: clothing the naked, feeding the hungry, giving shelter to the homeless, taking care of the sick…etc.
For one’s faith to be deemed ‘complete’, one must practice both sides; serve God, worship Him, and extend a helping hand to others; preach what one learns in church/from the scriptures. In the bible verse above, Jesus refers to the entrance to heaven as the narrow door, and He goes further to explain that not many will be able to go in.
In Matthew 7:21 Jesus says, “Not everyone who calls me ‘Lord, Lord’ will enter the kingdom of heaven, but only those who do what My Father in heaven wants them to do.” This is because, when it comes to matters faith, many practice only one side; attending mass every Sunday, but the instant one leaves the church premises they forget everything they learned. For instance, one could be so faithful when it comes to tithing, but if a hungry man was to walk up to them asking for food, they would chase them away heartlessly. This is why Jesus calls it the narrow door.
Jesus asks us to go through the narrow gate, because the gate to hell is wide and the road that leads to it is easy, and there are many who travel it, whereas the gate to life is narrow and the way that leads to it is hard and there are few people who find it (Matthew 13-14).
Faith is all about synchronizing one’s action with their firm belief in God. In 1 John 4:20-21 he says, “If someone says he loves God, but hates his brother, he is a liar. For he cannot love God, whom he has not seen, if he does not love his brother, whom he has seen. The command that Christ has given us is this: Whoever loves God must love his brother also.” We are asked to love our neighbours as much as we love ourselves, but above all, to love God with our whole being; that is the definition of a true believer.
