Jesus prayed, "And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent," John 17:3. The more we know the character of God and of Jesus; the closer we walk with them in intimate fellowship; the greater our understanding of God's word, the Bible; the greater will we appreciate the meaning in life.
God knows everything about you. Psalm 139:1-6, "You have searched me, LORD, and you know me. You know when I sit and when I rise; you perceive my thoughts from afar… you are familiar with all my ways. Before a word is on my tongue you, LORD, know it completely. You hem me in behind and before, and you lay your hand upon me. Such knowledge is too wonderful for me, too lofty for me to attain." If even "the very hairs of your head are numbered," (Matthew 10:30), certainly, God has a meaning for your life.
But “of what importance is the human race, that you should notice them? Of what importance is mankind, that you should pay attention to them, and make them a little less than the heavenly beings (angels)? You grant mankind honor and majesty; you appoint them to rule over your creation; you have placed everything under their authority, including all the sheep and cattle, as well as the wild animals, the birds in the sky, the fish in the sea and everything that moves through the currents of the seas,” Psalm 8:4-9 (NET).
Originally, God gave Adam and Eve the whole earth to rule (Genesis 1:28). When they sinned, they (and all their progeny) lost their dominion. It will be when mankind returns to love and obey God, that God will restore their dominion, and grant them understanding of their purpose and meaning.
This is what God's kingdom will be like, “Close your eyes for a moment to the scenes of misery and woe, degradation and sorrow that yet prevail on account of sin, and picture before your mental vision the glory of the perfect earth. Not a stain of sin mars the harmony and peace of a perfect society; not a bitter thought, not an unkind look or word; love, welling up from every heart, meets a kindred response in every other heart, and benevolence marks every act. There sickness shall be no more; not an ache, nor a pain, nor any evidence of decay–not even the fear of such things. Think of all the pictures of comparative health and beauty of human form and feature that you have ever seen, and know that perfect humanity will be of still surpassing loveliness. The inward purity and mental and moral perfection will stamp and glorify every radiant countenance. Such will earth's society be; and weeping bereaved ones will have their tears all wiped away," from The Divine Plan of the Ages, page 191.
