"Without visible landmarks, human beings tend to walk in circles. Without spiritual landmarks, mankind wanders as well. Without the word of God, we walk in circles." -Elder Uchtdorf
I may not be sure about a lot of things, I may have questions, even the occasional doubt, but I do know this is true.
We are given guidance through the scriptures, through sheer obedience. Often, I dont fully comprehend why I must be obedient, why I must follow certain rules or commandments, but I do know this, that the humble and meek will inherit the kingdom of heaven, the pure in heart will see the face of God. Even when we dont understand way we must be obedient, we must remember to be as a child, meek and submissive to his will. It is when we do this that we cease to walk in circles and begin to walk forward, towards a loving God, a loving Father, a father who see's our full potential and gives us these commandments so that we can reach that potential.
