This is a command from God, not to be lightly disregarded. It is universal, for it includes all men, everywhere. It is a solemn warning that the day is coming when every person will be judged by his personal relationship to Christ. And the pledge of its fulfillment is the fact of His resurrection, for Christ did not die in vain.
Salvation is personal and individual.
Jesus did not die to save society, but to save sinners. He was made in the likeness of man that He might take the place of each one of us upon the cross and bear the penalty of our personal guilt. The historic fact that Jesus came once in accordance with prophecy is proof that He will come again in accordance with prophecy, for both advents are included in the same prophecy. Isaiah saw the two-advents in line, like distant mountain peaks, and could not distinguish the time interval between them. The present interval between these two advents is the day of grace in which we live, and choose our eternal destiny.
