"For since the beginning of the world men have not heard, nor perceived by the ear, neither hath the eye seen, O God, beside thee, what He hath prepared for him that waiteth for Him" (Isaiah 64:4).
This beautiful Old Testament promise has been appropriated by Paul (I Corinthians 2:9) and applied to the New Testament believer guided by the indwelling Spirit of God. It looks forward to the ages to come when all those "things which God hath prepared for them that love Him" will be given in their fullness.
It is noteworthy that both "the beginning of the world" in our text (Isaiah 64:4) and "world without end" (45:17) are translations of the same Hebrew word, olam, which means, essentially, "indefinitely long age" or even "eternity." Thus the wonderful plan God has prepared for His people, to be implemented and enjoyed in eternity future, was formulated by Him in eternity past.
We were, then, chosen "in Him before the foundation of the world, that we should be holy and without blame before Him in love" (Ephesians 1:4). He had even planned our redemption from sin, through His Son, "with the precious blood of Christ, . . . Who verily was foreordained before the foundation of the world, but was manifest in these last times for you" (I Peter 1:19-20).
We may not, in this life, really comprehend with our minds such marvelous things, but we who "wait for Him" can believe them with rejoicing in our hearts, for "God hath revealed them unto us by His Spirit: for the Spirit searcheth all things, yea, the deep things of God" (I Corinthians 2:10). Thus we can unite with thankful and understanding hearts in Paul's great doxology: "Unto Him be glory in the church by Christ Jesus throughout all ages, world without end. Amen" (Ephesians 3:21). HMM
