Matthew 22:1-14 – Do I have eternal life?
1and again, Jesus spoke to them in parables, saying, 2 “The kingdom of heaven may be compared to a king who gave a wedding feast for his son, 3 and sent his servants to call those who were invited to the wedding feast, but they would not come. 4 Again he sent other servants, saying, ‘Tell those who are invited, “See, I have prepared my dinner, my oxen and my fat calves have been slaughtered, and everything is ready. Come to the wedding feast.”’ 5 But they paid no attention and went off, one to his farm, another to his business, 6 while the rest seized his servants, treated them shamefully, and killed them. 7 The king was angry, and he sent his troops and destroyed those murderers and burned their city. 8 Then he said to his servants, ‘The wedding feast is ready, but those invited were not worthy. 9 Go therefore to the main roads and invite to the wedding feast as many as you find.’ 10 and  those servants went out into the roads and gathered all whom they found, both bad and good. So the wedding hall was filled with guests.
11 “But when the king came in to look at the guests, he saw there a man who had no wedding garment. 12 and  he said to him, ‘Friend, how did you get in here without a wedding garment?’ and he was speechless. 13 Then the king said to the attendants, ‘Bind him hand and foot and cast him into the outer darkness. In that place, there will be weeping and gnashing of teeth.’ 14 For many are called, but few are chosen.”
(Matthew 22:1-14, ESV)
13“Then one of the elders addressed me, saying, “Who are these, clothed in white robes, and from where have they come?” 14 I said to him, “Sir, you know.” and he said to me, “These are the ones coming out of the great tribulation. They have washed their robes and made them white in the blood of the Lamb.
(Revelation 7:13-14, ESV)
7 Let us rejoice and exult and give him the glory, for the marriage of the Lamb has come, and his Bride has made herself ready; 8 it was granted her to clothe herself with fine linen, bright and pure"-- for the fine linen is the righteous deeds of the saints. (Revelation 19:7-8 ESV)
