Ephesians 1:9 making known to us the mystery of his will, according to his purpose, which he set forth in Christ
Having made known unto us the mystery of his will,…. The Gospel, which is a mystery, a hidden mystery, the mystery of God and of Christ, and the mystery of the Gospel. Four thousand years mankind and in especially the Jew were shrouded in a mystery, their men of wisdom and well versed in the law, who had been raised with all the knowledge of God that man processed and the “Good News ” was still a mystery. The shroud has been pulled back and the mystery revealed. Yet man is reluctant to embrace the revealed mystery. For four thousand years the Jewish people were under the law, and it was conditional, why? God was showing mankind they were incapable of keeping the law. Although it was conditional God had his elect who by faith and the promise look forward to the messiah. God understands the nature of man, and how man is work originated and if it was up to man they would still insist on good works to get saved.
There are many glimpses of the Mystery of the Gospel, in the Old Testament, to name a few. When the Israelites were in captivity in Egypt, which represent our captivity to sin, when God through Moses instructed them to put blood around their door post to protect them from death, one of the mystery is the Blood of Christ saves us from death. The story of Noah, who when God was bringing judgement on mankind, seal Noah and His family in an ark and protected them from judgement. This is a good illustration of our being seal with the Holy Spirit our guarantee of deliverance from God’s wrath and our perseverance. But most of all the mystery of the Gospel reveals God’s will; The Gospel is the mystery of the will of God; of his will in saving sinners by Christ; and it declares that he does all things in salvation, according to his sovereign will and pleasure; chooses, redeems, justifies,and glorifies, pardons, and calls whom he pleases; and this is made known by the ministry of the word, and by the Spirit, as a spirit of wisdom and revelation, in the knowledge of Christ and his Gospel: the discovery of which is, It is said that every man loves a mystery, that man has to be challenged to motivated His desire, yet this mystery transcends man wildest dream, that God in His riches and mercy would offer a free gift of eternal life through Jesus Christ His Son. That all sins past present and future would imputed to Christ on the cross, and he would impute His righteousness to us so we could stand blameless before a Holy God.
According to his good pleasure, which he hath purposed in himself; both with respect to the persons to whom it is made known, and with respect to the time when he makes it known; both these are as he pleases, and as he has purposed in his own heart; the Gospel is sent when and where he has determined within himself it shall go; and persons are called by it according to his purpose and grace.
