So, how do we explain the words of Jesus?
Matthew 10:12) And when ye come into an house, salute it.
13 .) And if the house be worthy, let your peace come upon it: but if it be not worthy, let your peace return to you.
14 .) And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.
15 .) Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city.
Matthew 18:1) At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven?
2 .) And Jesus called a little child unto him, and set him in the midst of them,
3 .) And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven.
4 .) Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.
5 .) And whoso shall receive one such little child in my name receiveth me.
6 .) But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea.
7 .) Woe unto the world because of offences! for it must needs be that offences come; but woe to that man by whom the offence cometh!
Luke 17:1) Then said he unto the disciples, It is impossible but that offences will come: but woe unto him, through whom they come!
2 .) It were better for him that a millstone were hanged about his neck, and he cast into the sea, than that he should offend one of these little ones.
Mark 3:28) Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme:
29 .) But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation:
And the words of John:
1st John 5:13) These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
14 .) And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:
15 .) And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
16 .) If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.
17 .) All unrighteousness is sin: and there is a sin not unto death.
AND IF THERE ARE DIFFERENT LEVELS OF REWARDS IN HEAVEN, WHY NOT DIFFERENT LEVELS OF SIN?
Romans 2:5) But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God.
6 .) Who will render to every man according to his deeds:
7 .) To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
8 .) But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
9 .) Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
10 .) But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
1st Corinthians 3:7) So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase.
8 .) Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.
9 .) For we are labourers together with God: ye are God's husbandry, ye are God's building.
10 .) According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon.
11 .) For other foundation can no man lay than that is laid, which is Jesus Christ.
12 .) Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
13 .) Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
14 .) If any man's work abide which he hath built thereupon, he shall receive a reward.
