1 Thes. 1:4 Knowing, brethren beloved, your election of God. 5 For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake. The gospel comes many times to many people "in word only" (general non-effectual call) without "power, and in the Holy Ghost, and in much assurance". Indeed, that is how it most often comes from the lips of men as most, and in some cases, all their audiance rejects it and go away as lost as when they came. Notice, Paul is instructing the church at Thessalonica how they can "know" their "election of God." The gospel does not come in "word only" when it is God's elect time to save them. It comes "in power' and it comes "in the Holy Ghost" and it comes "with much assurance." This last element proves it comes savingly as "assurance" cannot be given a lost person to "know....their election of God." This is the calling of Romans 8:30 where ALL God foreknew were ALL predestinated to be conformed to the image of His Son and ALL who were predestinated to be conformed to the image of His dear Son were ALL called and ALL justified and ALL glorified. He is talking about His "elect" as he goes on to say who shall lay anything to "God's elect" because it is Christ that "justifies THEM." To the Corinthians he told them to "see your calling" that "NOT MANY" wise or noble are "CALLED BY GOD" but "GOD HATH CHOSEN" those He calls and they are the offscouring of the world and He called them purposely to confound the wise and remove any grounds for glorying in anything but God's grace. 26 For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called: 27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; 28 And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are: 29 That no flesh should glory in his presence. 30 But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: 31 That, according as it is written, He that glorieth, let him glory in the Lord. If this is not an effectual call then how can Paul say that God does not call "many" who are of a certain class???
