Christ died for our sins according to scripture !
1 Cor 15:3-4
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he rose again the third day according to the scriptures:
This means old testament types serve as an enlightenment on the extent and efficacy of Christ atoning death.
Remember what Paul wrote 1 Tim 3:16
16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correctionn, for instruction in righteousness:
We will be looking at from scripture the doctrine of atonement.
Lets look at Noah's Ark, a type of Christ. 1 Pet 3:20-21
20 Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.
21 The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
No doubt this is a clear and unmistakable reference to Noah and the Ark passing through the judgmental flood in connection with the atoning death and justifying resurrection of Jesus Christ. The pattern of the Ark was given to Noah in minute detail by the Sovereign LORD (Gen. 6:14-16). Now the question is, was the ark adequate in size to allow for all who were living on the earth at that time? We all surely know the answer to that.
It was not God's purpose to save all of Mankind in the Ark, but only Noah and his family, and seeing there is no negligible quantity in The LORD, all the room and sufficiency sovereignly fitted in the ark for flood survival was fully put to use. Noah was "a preacher of righteousness," and while the ark was "a preparing," Noah preached Christ by emblem and sermon; for to preach righteousness is to preach Christ, for He is the believer’s justifying righteousness (1 Cor. 1:30; 2 Cor.5:21).
No doubt during this long period of one hundred and twenty years of Ark building, Noah admonished others as he was warned of God (Heb 11:7). However, only seven believed his report and they were of his own house (Gen 7:1). Then God brought judgment upon the world of the ungodly and they perished in the flood (2 Pet 2:5). The Noachian household is a type of the household of God (Eph 2:19), and Christ, the anti type of the Ark (Acts 4:12) and Head "over His own house" (Heb. 3:6), has made adequate room for His family and none else. Christ is the Sovereign who having eternally loved His progeny, He made room for them and them alone in ark of His mercy and grace. The Ark as a type was not given to us in abbreviated fashion, but in minute thoroughness, and every detail points to Christ.
Atonement sufficiency is founded in God’s forelove, and Christ loves only those who were given to Him by the Father in the covenant of redemption (Jer 31:3 ; John 13:1 , 17:6 ; Rom. 8:37). In the redemptive design there is no such thing as uncovenanted love, and hence no universal atonement sufficiency.
The Ark was a divine arrangement made before the waters of judgment fell from heaven, and in building the Ark, Noah followed the Divine specifications with exactitude. "Thus did Noah; according to all that God commanded him,’ so did he" (Gen. 6:22). There was not one extra cubic inch in the completion of the Ark, nor was there any wasted space. The sufficiency of the Ark was according to God’s purpose, and His elective purpose was to save only eight souls from the flood (1 Pet 3:20).
In like manner, Jesus Christ was furnished by God before the foundation of the world to deliver His people from the storm of judgment of the wrath to come (1 Pet 1:20; 1 Thess 1:10). Christ’s mission to this earth, as was the Ark, was according in every detail to the necessity of His people, and not one thing wrought by the atoning death of Christ was extended beyond those for whom He died. The sufficiency and efficiency of Christ’s offering was eternally concluded to the elect of God, and there was no redemptive sufficiency for the rest. The purpose of atoning sufficiency must be determined by its achievement, and it has none beyond "the Church of God, and the sheep of His hand." (Acts 20:28; Ps 95:7).
This Type is especially instructive since The Lord compares the time of His return with that of the days of Noah, Matt 24:37-38
37 But as the days of Noah were, so shall also the coming of the Son of man be.
38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,
