When I was in my second year of high school, one of my classmates came down with tetanus and died. He was a diligent student. I believe he will be able to enjoy the happiness of Heaven as he made good use of the time that God gave him. God looks at the quality of one's life. Whether we spend a long time or short time in this life, if we do our best, the happiness that God will give us will still be perfect. "Comparisons are odious." We need not compare ourselves with others in everything. Often, it seems that God favours one more than the other. However, God is just. Every bestowed grace still requires our persevering efforts.
