Many times when someone mistreats us, the first thing that we want to do, is do the same to them. I'm guilty of thinking that way myself at times. However, just because we think that, is it really the best thing to do?
Definitely not! Our thoughts don't have to control us. We should step away from the issue and clear our minds. With a much clearer mind, those thoughts will fade away.
1 Peter 3:8-9 English Standard Version Bible
8 Finally, all of you, have unity of mind, sympathy, brotherly love, a tender heart, and a humble mind.
9 Do not repay evil for evil or reviling for reviling, but on the contrary, bless, for to this you were called, that you may obtain a blessing.
