First, is my interpretation of what this passage actually means. To me it rings of the attribute of obedience. More times than I can count, walking in the ways of the Lord are directly linked to keeping all His commandments and His laws. Yet obedience is more than just keeping the commandments and standing worthy of a temple recommend. That is the first level of obedience. The preparatory level if you will. The second level is complete obedience and submission to God's will. It is not only submitting your will to God but it is wanting what He wants for you that is, aligning your will with His. It is not praying for what you want and hoping God allows it, rather it is praying to know what God wants for you.
I have had far too many experiences with this but one of late has been very difficult. Recently I had to let someone go. Someone I loved very much. Not because I didn't care about them or because I didn't want them in my life but because I knew they were holding me back. That, while God was paces away beckoning me to walk with Him, I was attempting to keep up with a large stone shackled to my foot. What was worse is that the more frantically God called to me the more I tightened the chain because I wanted to have both. I wanted to completely dedicate my heart and soul to Him and still hang on to this person. Yet I have come to a realization, as hard as it is, that I cannot have both. I have learned that if I am to walk the road of discipleship this person cannot come with me.
Some may say that I am interpreting God's will incorrectly but honestly, as I have traveled down this path, freeing myself of this burdensome stone and ran towards my Father and my Savior I have felt freedom and joy that I can't quiet explain. More than that I feel peace. Peace that I am becoming more like Him. That is my ultimate goal. I go forward with certainty that I will be able to give God every thing, including my heart, while I am gone. Some day there will be someone. A worthy, righteous priesthood holder that walks with God also and we will walk together, towards the Celestial Kingdom and our Lord.
