Jesus taught an important lesson about relationships. Essentially, what He said is that if any of us tries to improve a relationship by getting the other person to change (working hard to get the speck out of the other person’s eye), energies are being expended in the wrong direction. The place to begin is with our own failures (the plank or beam in one’s own eye).
Alone with God, simply ask, “Lord, what’s wrong with me? What are my faults? What are my sins?” Get your pencil and paper ready, for that is a prayer God will answer. Make a list of your sins.
Go back over the list and agree with God that these are wrong and, at the same time, thank Him for Christ’s death on the cross and therefore for forgiveness. Work through your list and accept God’s forgiveness for every past failure. God does not intend us to live under the emotional load of past failures. We can be forgiven....
Any time you become aware of friction or ill feelings in your relationships, the first question should be “Lord, what’s wrong with me?” As you see where you are wrong, confess it, accept God’s forgiveness, and ask His Spirit to control you. People do not “make us miserable.” We choose to be miserable. The immediate emotion that arises after the action of another person may be automatic and beyond your control, but what you do with that emotion is your decision. If you are willing to search your own heart and confess any wrong discovered, then you can feel at peace, even though you are not particularly happy with the situation at hand. You then can be a positive force for change, rather than compounding the problem with your attitude.
