Bible. Free will (Freedom of choice)
Being created, every person will always exist and will never disappear anywhere. Man is the image and likeness of God. The Creator does not make mistakes.
Person was given free will, freedom of choice. Living on this Earth a person can freely turn to God and know Him. If we will not do this during life, we will know the Creator after death, in torment. In any case, a person's conversion to God will be free.
During our life on Earth, the Lord revealed to us His law, commandments: “thou shalt love the LORD thy God
with all thine heart, and with all thy soul, and with all thy might”
If we freely choose to be the children of the Lord, we turn to Him as our Father, and sincerely, with all our heart, we ask Him for forgiveness for all iniquity, for all the sins that we have committed, then He punishes us moderately: “correct thee in measure;
yet will I not leave thee wholly unpunished”
On the other hand, in this life we can neglect God, we can abhor His law, profane ourselves by sins and not resort to purgatory repentance. In this case we will turn to the Lord God the Creator and know Him “after death by pain”
To know God during life or after death
10 For such as in their life have received benefits, and have not known me;
11 And they that have loathed my law, while they had yet liberty, and, when as yet place of repentance was open unto them, understood not, but despised it;
12 The same must know it after death by pain.
Love the LORD your God with all your heart
4 Hear, O Israel: The LORD our God is one LORD: Mar 12, 29.
5 And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might. Mat 22, 37. Mar 12, 30. Luk 10, 27.
6 And these words, which I command thee this day, shall be in thine heart: Deu 4, 9.
Who is warning to flee from the righteous wrath
During the time of John the Baptist, the Pharisees were considered righteous and were very revered among the people. John exposes their outward righteousness and points out that instead of being the seed of the woman, they became the seed of the serpent: “generation of vipers”
7 But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come? Mat 23, 33. Luk 3, 7.
8 Bring forth therefore fruits meet for repentance:
