“For other foundation can no man lay than that is laid, which is Jesus Christ.”
King James Version (KJV)
3:11 For other foundation - On which the whole church: and all its doctrines, duties, and blessings may be built. Can no man lay than what is laid - In the counsels of divine wisdom, in the promises and prophecies of the Old Testament, in the preaching of the apostles, St. Paul in particular. Which is Jesus Christ - Who, in his person and offices, is the firm, immovable Rock of Ages, every way sufficient to bear all the weight that God himself, or the sinner, when he believes, can lay upon him.
1Co 3:11 Other foundation can no man lay, etc. There is only one foundation of the church (Mt 16:16). This foundation-stone was laid by God (Isa 28:16). Paul's work under God was to point to this foundation, to induce them to believe, and thus to build them upon it. His preaching laid it in their hearts. To preach Christ is to preach the fundamental or foundation truth of the church.
