The Holy Spirit, who indwells every believer, gives us a foretaste of the coming glory of heaven. He is therefore called the “earnest” or pledge of the inheritance we shall receive by Gods grace in eternity (Eph. 1:13,14). In biblical times, the word “earnest” was a trade term for the initial payment on a debt. It was made as a promise that full payment would be forthcoming. In principle, then, when an earnest was given, the final installment was guaranteed. Likewise, the joy we experience now through Gods Spirit is just a kind of first installment of the rich blessings that His children will receive in eternity.
A wealthy man called his faithful assistant into his office one day and said, “Ive put your name in my will, and someday youll receive $10,000. Since it may be a while before you get that legacy, I want to make you happy now by paying you the interest on that amount each year. Here is a check for $600 as a starter.” The surprised clerk was doubly grateful. The prospect of the inheritance was certainly good news, but the money he received in advance gave him complete assurance that someday the entire $10,000 would be his.
As Gods children, lets rejoice in the riches we now have in Christ through the Holy Spirit. He is our guarantee of the “exceeding and eternal weight of glory” that our Heavenly Father will one day give to the heirs of salvation (2 Cor. 4:17). Our present blessings are but a token of the greater inheritance we will eventually receive.
