Unforgiveness is an absolute barrier to blessing. And you know what? It doesn’t matter if the person you refuse to forgive is even still alive. Their status is not what concerns God, it’s yours. As long as you refuse to forgive ANYONE, blessing cannot get to your heart. You’ve built a big old wall that keeps it out.
Holding onto unforgiveness is poison to your soul. Seriously. It’s like cancer. It will infect your thinking and your actions. It is not of God. Nowhere will you find Jesus ever teaching about it being ok to not forgive. What does He say? The opposite. And forgive us our debts, as we forgive our debtors. (Mat 6:12) We are taught to forgive. And as many times as it takes. (Mat 18:22)
Ask God to show you right now if you have not forgiven someone you should have. Don’t mess around with this. That memory you just got? Deal with it. Tell God that you forgive that person. Ask the Lord to forgive you for not doing it sooner. Clean the slate. Good. Now it’s done. Ask God to help you be sensitive every time you need to forgive someone. You’ll be surprised when your realize that it’s every day. That’s ok. Just do it. And as you do, you’ll start to see the blessings from God start to come to you.
