Jesus is always calling men to come to him. The door has been opened to whosoever will respond to the call and be born from above. The life of Jesus and the love of the brethren, to know God is the greatest privilege we could ever have.
But there is another side for those who will refuse the life of Christ Jesus.
Matt 7:15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. 16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? 17 Even so every good tree brings forth good fruit; but a corrupt tree brings forth evil fruit. 18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. 19 Every tree that brings not forth good fruit is hewn down, and cast into the fire. 20 Wherefore by their fruits ye shall know them.
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that does the will of my Father which is in heaven. 22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? 23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Matt 25:41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels: 42 For I was an hungered, and ye gave me no meat: I was thirsty, and ye gave me no drink: 43 I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not. 44 Then shall they also answer him, saying, Lord, when saw we thee an hungered, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee? 45 Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me. 46 And these shall go away into everlasting punishment: but the righteous into life eternal.
Luke 13:24 Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able. 25 When once the master of the house is risen up, and hath shut to the door, and ye begin to stand without, and to knock at the door, saying, Lord, Lord, open unto us; and he shall answer and say unto you, I know you not whence ye are: 26 Then shall ye begin to say, We have eaten and drunk in thy presence, and thou hast taught in our streets. 27 But he shall say, I tell you, I know you not whence ye are; depart from me, all ye workers of iniquity. 28 There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you yourselves thrust out. 29 And they shall come from the east, and from the west, and from the north, and from the south, and shall sit down in the kingdom of God. 30 And, behold, there are last which shall be first, and there are first which shall be last.
In these three separate discussions, Jesus makes clear that there will be some who protest at the fact they are being rejected. It is clearly stated that they are not known, that they are workers of iniquity and that they cast out of His presence.
It is a fearful thing to think that you could be one of these.
Humble yourself in the sight of the Lord, call upon him, and he will answer, repent of your sin and put your trust in him. Receive the love that he has given, do not strive to earn from him, but freely receive what he has given.
