Dont bring it up again.

Mark 11:25 (AMP) "And whenever you stand praying, if you have anything against anyone, forgive him and let it drop (leave it, let it go), in order that your Father Who is in heaven may also forgive you your [own] failings and shortcomings and let them drop." Has anyone ever sinned against you? If you're a human being, then the answer is yes.... It happens all the time. Instead of bringing up people's mistakes over and over again after it happens, let it go!! Just drop it, the same way God does to our sins! He forgives and forgets! Bringing up people's past sins does not make anything better, but instead makes it worse! When you sin against someone, you should ask for forgiveness and move on. If someone sins against you, whether they ask for forgiveness of not, forgive them and move on!
