He replied, 24 “Work hard to enter the narrow door to God’s Kingdom, for many will try to enter but will fail. 25 When the master of the house has locked the door, it will be too late. You will stand outside knocking and pleading, ‘Lord, open the door for us!’ But he will reply, ‘I don’t know you or where you come from.’ 26 Then you will say, ‘But we ate and drank with you, and you taught in our streets.’ 27 And he will reply, ‘I tell you, I don’t know you or where you come from. Get away from me, all you who do evil.’
28 “There will be weeping and gnashing of teeth, for you will see Abraham, Isaac, Jacob, and all the prophets in the Kingdom of God, but you will be thrown out. 29 And people will come from all over the world—from east and west, north and south—to take their places in the Kingdom of God. 30 And note this: Some who seem least important now will be the greatest then, and some who are the greatest now will be least important then.” (Luke 13:22-30 NLT)
There is only one way to enter into God's eternal kingdom, through the door of faith. Our good works can't open the door. Our bad works shut the door. Jesus opened the door for all who believe in Him. We are saved by grace through faith in Jesus Christ. Jesus calls us to follow Him, to trust Him, to receive His gifts of forgiveness, love and faith.
