Say, lets take a look at some other views: St. Thomas Aquinas, Doctor of the Church. Here is a pretty good summary of his commentary from Summa Theologia:
Thomas identified the goal of human existence as union and eternal fellowship with God. This goal is achieved through the beatific vision, in which a person experiences perfect, unending happiness by seeing the essence of God. The vision occurs after death as a gift from God to those who in life experienced salvation and redemption through Christ.
