If you can't forgive others then do not expect others to forgive you. More importantly, read Mark 11:26 and let that sink in. "But if ye do not forgive, neither will your Father which is in Heaven forgive you." In other words, you will be forgiven by the same measure that YOU forgive. Remember, you will only give account for your own actions and not the actions of others. Do not hold grudges and allow actions of others to interfere with your walk with God.
"I used to hold grudges until I realized that most people are narcissistic and their actions are driven by an unhealthy self-interest and not maliciousness towards me. I have since freed myself from this needless burden." - Steve Maraboli #quote
