And when you stand praying, if you hold anything against anyone, forgive them, so that your Father in heaven may forgive you your sins. Mark 11:25, NIV
If you are not getting answers to your prayers, check yourself very thoroughly and honestly as to whether you have resentments in your mind.
Spiritual power cannot pass through a personality where resentment exists. Hate is a non-conductor of spiritual energy.
I suggest that every time you pray, you add this phrase, “Lord, take from my thought all ill will, grudges, hates, jealousies.” Then practice casting these things from your thoughts.
~ ~ Norman Vincent Peale
What we hold against another is a strong soul blocker. The Holy Spirit cannot, no, will not, penetrate into that darkness. Much is said throughout the bible on unforgivenss. It is a sin against the second law – love your neighbor. Who is our neighbor? Well, who isn’t? Holding any resentment, anger, unforgivenes…against another is a slap in the face of God. Look at all he has forgiven and continues to forgive us for.
Reflect: Is there any (list different ways you hold something against another, i.e. resentment, envy, jealousy, etc) in your heart towards another. Forgive immediately, not for them but for your own soul. For what God has done for you.
