False. Jesus says very clearly, in no ambiguous language, if you do not forgive those who have wronged you, you will not be forgiven.
Matthew 6:12
"And forgive us our debts, as we also have forgiven our debtors."
Matthew 6:15
"But if you don’t forgive others, your Father will not forgive your offenses."

"So also my heavenly Father will do to you unless every one of you forgives his brother or sister from your heart.”"
Luke 6:37
"Forgive, and you will be forgiven."
Luke 17:3-4
"Be on your guard. If your brother sins, rebuke him, and if he repents, forgive him. And if he sins against you seven times in a day, and comes back to you seven times, saying, ‘I repent,’ you must forgive him."
2 Corinthians 2:5-7
"If anyone has caused pain, he has caused pain not so much to me but to some degree—not to exaggerate—to all of you. This punishment by the majority is sufficient for that person. As a result, you should instead forgive and comfort him."
Colossians 3:12-13
"Therefore, as God’s chosen ones, holy and dearly loved, put on compassion, kindness, humility, gentleness, and patience, bearing with one another and forgiving one another if anyone has a grievance against another. Just as the Lord has forgiven you, so you are also to forgive."
