Here we have two grand cardinal truths laid down, namely, first, the believer is God's workmanship; and secondly, God has given him the earnest of the Spirit. Most marvellous — most glorious facts! Facts which demand the attention of the reader. Everyone who simply and heartily believes on the Lord Jesus Christ is God's workmanship. God has created him anew in Christ Jesus. Clearly, therefore, there can be no possible ground for questioning his acceptance with God, inasmuch as God can never call in question His own work. He will, assuredly, no more do this in His new creation, than He did in the old. When God looked upon His work, in the opening of the Book of Genesis, it was not to judge it or call it in question, but to announce it very good, and express His complacency in it. So now, when God looks upon the very feeblest believer, He sees in him His own workmanship, and most assuredly, He is not going, either here or hereafter, to call in question His own work. God is a rock, His work is perfect, and the believer is God's work; and because he is His work He has sealed him with the Holy Ghost.
