Many students enter college with the hope of excelling. Finding themselves surrounded by talented, bright, attractive people, they push harder for perfection academically, socially, physically, as well as perfect utilization of time and resources.
Perfection is seen as the price for success and avoidance of disappointments and problems.
Instead of feeling joy in their progress, they often experience depression, anxiety, and a constant fear of failure. The Savior's injunction to be perfect implied a wholeness or completeness that would only be fully attained through the resurrection. It will take us ages to accomplish this end, for there will be greater progress beyond the grave, and it will be there that the faithful will overcome all things, and receive all things, even the fullness of the Father's glory. Only the Lord Jesus attained that state, and he had an advantage that none of us had. He was the Son of God, and he came into this life with a spiritual capacity and an inheritance that exceeded beyond all comprehension what any of the rest of us was born with.
