God's gifts are many; His best gift is one. It is the gift of Himself. Above all gifts, God desires most to give Himself to His people. Our nature being what it is, we are the best fitted of all creatures to know and enjoy God. "For Thou madest us for Thyself, and our heart is restless, until it repose in Thee" (from The Confessions of St. Augustine). When God told Aaron, "You will have no inheritance in their land, nor will you have any share among them; I am your share and your inheritance among the Israelites," He in fact promised a portion infinitely above all the real estate in Palestine and all the earth thrown in (Numbers 18:20). To possess God--this is the inheritance ultimate and supreme.
There is a sense in which God never gives any gift except he gives Himself with it. The love of God, what is it but God giving Himself in love? The mercy of God is but God giving Himself in mercy, and so with all other blessings and benefits so freely showered upon the children of atonement. Deep within all divine blessing is the Divine One Himself dwelling as in a sanctuary.
