“‘The Lord is my portion,’ says my soul, ‘therefore I will hope in him.’” Lamentations 3:24 ESV
The word translated as "portion" from the Hebrew in which the Old Testament was written can be rendered, "portion, tract, territory, part, equal share." It can even refer to booty, as in the spoils of war.
To say that the Lord is my portion then seems to say that having a relationship with Him, to trust in Him, means that we have a share in His kingdom.
Today, it means, in part, that those who follow Christ have a share in the victory over sin and death He won over the cross, as well as a share in His eternal life. This assures us that, through Christ, God gives us a full and equal share as "heirs of God and co-heirs with Christ" (Romans 8:17). To have the Lord as our portion is to have everything: Life with God, full, eternal, never-ending, complete.
What an amazing, comforting, and inspiring thing! By grace through faith in Christ, we have a portion of the legacy of life, forgiveness, and eternity Christ died and rose to give!
"Therefore I will hope in Him."
