"Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you. “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.” (Matthew 7:1-5)
It is easy to see the wrong that someone else does, without first examining our own hearts to see what wrong we have done. It has been the course throughout history.
The best thing we can do is pray. Ask the Lord to check our own hearts to see if there is anything we need to correct within them and trust that if we have given our lives over to Him, He will help us to change whatever needs changing.
It’s not easy to forgive someone for hurting you. I think the more you love someone, the more it hurts. Maybe that is the measure? It may take time, it may take a lot of prayer or even fasting to get through it. Be honest with God, let Him know that you are struggling with this. Ask for His help. There are some things we can’t do in our strength, we need to ask Him for His. In forgiving someone it releases the “sting” of the pain of whatever the situation is and allows you to move forward resting in the knowledge that just as God has forgiven you, you have forgiven them, even if you have to start out by just faithfully saying what you are not yet feeling in your heart. As you verbalize it over and over again it will eventually happen to be a reality, in God’s time.
