One of the most important things to keep straight is the doctrine of salvation by the sovereign grace of God. We understand that man is totally depraved and apart from the sovereign grace of God, all men everywhere will remain unsaved. Our heavenly Father chose a people in eternity and gave them to His Son. The Eternal Son of God agreed to be the Savior of all those that the Father gave to him in eternity. God the Holy Spirit purposed with the Father and the Son to quicken those that the Father chose in Christ and that Christ died to save – by the means of the preaching of the gospel of the Lord Jesus Christ.
Eph 1:3-4 Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ: According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
John 6:37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
John 10:11 I am the good shepherd: the good shepherd giveth his life for the sheep.
Eph 2:1-5 And you hath he quickened, who were dead in trespasses and sins; Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others. But God, who is rich in mercy, for his great love wherewith he loved us, Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
Titus 3:5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
1 Peter 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
Rom 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
