This seal is constituted by _the Holy Spirit of the promise_,--in contrast with the material seal, “in the flesh, wrought by hand,”[51] which marked the children of the Old Covenant from Abraham downwards, previously to the fulfilment of the promise (Gal. iii. 14). We bear it in the inmost part of our nature, where we are nearest to God: “The Spirit witnesseth to our spirit.” “The Israelites also were sealed, but by circumcision, like cattle and irrational animals. We were sealed by the Spirit, as sons” (Chrysostom). The stamp of God is on the consciousness of His children. “We know that Christ abides in us,” writes St John, “from the Spirit which He gave us” (1 Ep. iii. 24). Under this seal is conveyed the sum of blessing comprised in our salvation. Jesus promised, “Your heavenly Father will give His Holy Spirit to them that ask” (Luke xi. 13), as if there were nothing else to ask. Giving us this, God gives everything, gives us Himself! In substance or anticipation, this one bestowment contains all good things of God. The apostle writes “the Spirit of the promise, _the Holy_ [Spirit],” with emphasis on the word of quality; for the testifying power of the seal lies in its character. “Beloved, believe not every spirit; but try the spirits, whether they are of God” (1 John iv. 1). There are false prophets, deceiving and deceived; there are promptings from “the spirit that works in the sons of disobedience,” diabolical inspirations, so plausible and astonishing that they may deceive the very elect. It is a most perilous error to identify the supernatural with the Divine, to suppose mere miracles and communications from the invisible sphere a sign of the working of God. Antichrist can mimic Christ by his “lying wonders and deceit of unrighteousness” (2 Thess. ii. 8-12). Jesus never appealed to the power of His works in proof of His mission, apart from their ethical quality. God’s Spirit works after His kind, and makes ours a holy spirit. There is an objective and subjective witness--the obverse and reverse of the medal (2 Tim. ii. 19). To be sealed by the Holy Spirit is, in St Paul’s dialect, the same thing as to be _sanctified_; only, the phrase of this text brings out graphically the promissory aspect of sanctification, its bearing on our final redemption.[52]
