I know a few of the reasons why the Lord requires us to listen to mortal servants. One of the reasons is that you and I need a check on our own inspiration occasionally. We can be mistaken. We at times, even with real intent and with faith and with careful prayer, may come to wrong conclusions. Listening to others can provide correction. It can promote more careful consideration. I hope you will always remember that there is safety in counsel.
Being 100 percent responsible is accepting yourself as the person in control of your life. If others are at fault and need to change before further progress is made, then you are at their mercy and they are in control over the positive outcomes or desired results in your life. Agency and responsibility are inseparably connected. You cannot avoid responsibility without also diminishing agency. Mercy and justice are also inseparable. You cannot deny the Lord’s justice without also impeding His mercy. Oh, how Satan loves to divide complementary principles and laugh at the resulting devastation!
