A day in thy courts Psa 84:10

In laymans terms, "why do our actions not follow our stated beliefs?", is that we are human and prone to sin. If that were not the case our Savior would not have suffered as he did on the cross for us. We must continually try to live the life expected, but the devil ( sinful nature) is always setting obstacles and temptations in the way. However we can't always be using that as an excuse. We must struggle, and strive, and fight the fight. There must be success in this struggle and success comes in the form of help from our Heavenly Father.
