Matthew 6:12 

New International Version (NIV)

¹² And forgive us our debts,
    as we also have forgiven our debtors.

Matthew 6:14-15 

New International Version (NIV)

¹⁴ For if you forgive other people when they sin against you, your heavenly Father will also forgive you. ¹⁵ But if you do not forgive others their sins, your Father will not forgive your sins.

Romans 12:2 

New International Version (NIV)

² Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.

Romans 12:19-21 

New International Version (NIV)

¹⁹ Do not take revenge, my dear friends, but leave room for God’s wrath, for it is written: “It is mine to avenge; I will repay,” says the Lord. ²⁰ On the contrary:

“If your enemy is hungry, feed him;
    if he is thirsty, give him something to drink.
In doing this, you will heap burning coals on his head.”

²¹ Do not be overcome by evil, but overcome evil with good.
