Job 14; Acts 9:22-43
When Esau was forty years old, he took as wives Judith the daughter of Beeri the Hittite, and Basemath the daughter of Elon the Hittite. And they were a grief of mind to Isaac and Rebekah. Genesis 26:34-35
Do you have relationships in your life that are "a grief of mind"? Think about those people who really challenge your thoughts. It is as if you just cannot get along with them no matter how hard you try and you cannot accept who they are or what they do no matter how much you pray. However, for some reason, you cannot escape the relationship either. These people quench our peace and rob us of joy. Why can we not just live life without personality conflicts?
The answer has to do with the two greatest commandments. We must love the Lord with all our hearts, minds, souls and strength and we must also love others as ourselves. Jesus says in Luke 6:32-36 that, if you love those who love you, what credit is that to you? For even sinners love those who love them. And if you do good to those who do good to you, what credit is that to you? For even sinners do the same. And if you lend to those from whom you hope to receive back, what credit is that to you? For even sinners lend to sinners to receive as much back. But love your enemies, do good, and lend, hoping for nothing in return; and your reward will be great, and you will be sons of the Most High. He is kind to the unthankful and evil. Therefore be merciful, just as your Father also is merciful.
God wants us to learn mercy, kindness, thankfulness and love. We cannot love God with everything we have and then not love others. We can have people in life that are a grief of mind but God desires that we learn to love with His heart, touch with His hands and see through His eyes. We can only do that through a dependency on the Lord through His Holy Spirit. God wants us to be more like Him and He can change us if we work with Him through all this.
To overcome these personal conflicts, try stepping back from the issues and pray that you can have a discernment to change the dynamics of the relationship. That person may not ever change but you can. Be proactive in prayer if you know that you will be interacting with that person and ask the Lord to check your spirit before you act out in the flesh. Slowly but surely, you will begin to have victory and God will receive the glory.
