It is only by His grace that we are saved and His gift of salvation.
41The Son of Man will send out his angels, and they will weed out of his kingdom everything that causes sin and all who do evil. 42They will throw them into the fiery furnace, where there will be weeping and gnashing of teeth.
Those who got the mark of the beast will be inflicted with painful sores.
Deuteronomy 28:27 The LORD will afflict you with the boils of Egypt and with tumors, festering sores and the itch, from which you cannot be cured.
In this life all us will experience tribulation. But this tribulation is different from the "great tribulation" we will experience at the end times. God will truly judge to all sinners. For example those who commit homosexuallity, adultery and whatever your sins are will be righteously judge.
The goodness of God will lead people to repentance. But if the people harden thier hearts when they hear His word and not allowing it to change thier ways then judgement will come to them.
Luke 13:3 I tell you, no! But unless you repent, you too will all perish.
Luke 13:5 I tell you, no! But unless you repent, you too will all perish."
Whatever our sins are if we repent truthfuly God will comfort us.
Matthew 5:14 You are the light of the world. Matthew 5:15c And it gives light to everyone in the house.Jesus teach us as His disciples that we are the LIGHT of the world. And indeed, He is our MODEL/EXAMPLE of being the LIGHT of the world. He is very consistent in living as a light by the Power of Holy Spirit.
When we take a look at ourselves, we are not consistent, we are not perfect. But we need to follow/go after Jesus because He said "I am the Light of the world whoever follows me will never walk in the darkness but will have the light of life." So let us follow Jesus and look to his attitude and obey His teachings.
