" You should focus on what you can change, not what you cannot change. What’s done is done. If somebody offended you, mistreated you, or disappointed you, the hurts can’t be undone. You can get bitter--pack it in a bag and carry it around and let it weigh you down--or you can forgive those who hurt you and go on.
If you lost your temper yesterday, you can beat yourself up--put the guilt and condemnation in a bag--or you can ask for forgiveness, receive God’s mercy, and do better today.
If you didn’t get a promotion you wanted, you can get sour and go around with a chip on your shoulder, or you can shake it off, knowing that God has something better in store.
No matter what happens, big or small, if you make the choice to let it go and move forward, you won’t let the past poison your future.
A woman I know went through a divorce years ago. We prayed several times in our services, asking God to bring a good man into her life. One day she met a fine Godly man, who was very successful. She was so happy, but she made the mistake of carrying all her negative baggage from her divorce into the new relationship. She was constantly talking about what she had been through and how she was so mistreated.
She had a victim mentality. The man told me later that she was so focused on her past and so caught up in what she had been through that he just couldn’t deal with it. He moved on. That’s what happens when we hold on to the hurts and pains of the past. It will poison you wherever you go. You can’t drag around all the personal baggage from yesterday and expect to have good relationships. You’ve got to let it go.
Quit looking at the little rearview mirror and start looking out the great big windshield in front of you. You may have had some bad breaks, but that didn’t stop God’s plan for your life. He still has amazing things in your future.
When one door closes, stay in faith and God will open another door. If a dream dies, don’t sit around in self-pity talking about what you lost, move forward and dream another dream. Your life is not over because you lost a loved one, went through a divorce, lost a job, or didn’t get the house you wanted. You would not be alive unless God had another victory in front of you. "
