IS IT NECESSARY FOR CHRISTIANS TO FORGIVE?

MATTHEW 6:12,14,15 RSV
12 And forgive us our tresspasses, As we also have forgiven our tresspassors
14 "For if you forgive men their trespasses, your heavenly Father will also forgive you.
15 "But if you do not forgive men their trespasses, neither will your Father forgive your
trespasses.

MATTHEW 18:21-35 NKJV
21 Then Peter came to Him and said, "Lord, how often shall my brother sin against me, and I
forgive him? Up to seven times?"
22 Jesus said to him, "I do not say to you, up to seven times, but up to seventy times seven.
23 "Therefore the kingdom of heaven is like a certain king who wanted to settle accounts with
his servants.
24 "And when he had begun to settle accounts, one was brought to him who owed him ten
thousand talents.
25 "But as he was not able to pay, his master commanded that he be sold, with his wife and
children and all that he had, and that payment be made.
26 "The servant therefore fell down before him, saying, 'Master, have patience with me, and I
will pay you all.'
27 "Then the master of that servant was moved with compassion, released him, and forgave him
the debt.
28 "But that servant went out and found one of his fellow servants who owed him a hundred
denarii; and he laid hands on him and took him by the throat, saying, 'Pay me what you owe!'
29 "So his fellow servant fell down at his feet and begged him, saying, 'Have patience with me,
and I will pay you all.'
30 "And he would not, but went and threw him into prison till he should pay the debt.
31 "So when his fellow servants saw what had been done, they were very grieved, and came and
told their master all that had been done.
32 "Then his master, after he had called him, said to him, 'You wicked servant! I forgave you all
that debt because you begged me.
33 'Should you not also have had compassion on your fellow servant, just as I had pity on you?'
34 "And his master was angry, and delivered him to the torturers until he should pay all that was
due to him.
35 "So My heavenly Father also will do to you if each of you, from his heart, does not forgive
his brother his trespasses."

MARK 11:25-26 NKJV
25 "And whenever you stand praying, if you have anything against anyone, forgive him, that
your Father in heaven may also forgive you your trespasses.
26 "But if you do not forgive, neither will your Father in heaven forgive your trespasses."

LUKE 11:4 NKJV
And forgive us our sins, For we also forgive everyone who is indebted to us. And do not lead
us into temptation, But deliver us from the evil one."

LUKE 17:3-4 NKJV
3 "Take heed to yourselves. If your brother sins against you, rebuke him; and if he repents,
forgive him.
4 "And if he sins against you seven times in a day, and seven times in a day returns to you,
saying, 'I repent,' you shall forgive him."

ROMANS 12:14-21 NKJV
14 Bless those who persecute you; bless and do not curse them.
15 Rejoice with those who rejoice, and weep with those who weep.
16 Be of the same mind toward one another. Do not set your mind on high things, but associate
with the humble. Do not be wise in your own opinion.
17 Repay no one evil for evil. Have regard for good things in the sight of all men.
18 If it is possible, as much as depends on you, live peaceably with all men.
19 Beloved, do not avenge yourselves, but rather give place to wrath; for it is written,
"Vengeance is Mine, I will repay," says the Lord.
20 "Therefore if your enemy hungers, feed him; If he thirsts, give him a drink; For in so doing
you will heap coals of fire on his head."
21 Do not be overcome by evil, but overcome evil with good.

EPHESIANS 4:32 NKJV
And be kind to one another, tenderhearted, forgiving one another, just as God in Christ also
forgave you.

COLOSSIANS 3:12-13 NKJV
12 Therefore, as the elect of God, holy and beloved, put on tender mercies, kindness,
humbleness of mind, meekness, longsuffering;
13 bearing with one another, and forgiving one another, if anyone has a complaint against
another; even as Christ forgave you, so you also must do.
