The sin of Adam brought death upon those descended from him (all of us). Before this there was no disease, suffering, or death: “Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: . . . For the wages of sin is death; . . .” Romans 5:12-6:23
However, God has not left us without hope: “But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.” Romans 5:8
The Lord Jesus Christ is fully God, and has been eternally. (Micah 5:2; John 8:58; Ps. 102:24-27; Heb. 1:8-12 with Isaiah 44:24). Jesus (while remaining by nature God) also became a man (“of the seed of David”) and lived a sinless life. He bore our sins in his body on the cross (Isaiah 53; 1 Peter 2:24), and was bodily raised (John. 2:19-22; Luke 24:39; Rom. 1:3 with 2 Tim 2:8).
“For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures: And that he was seen of Cephas, then of the twelve: After that he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep. After that, he was seen of James; then of all the apostles. And last of all he was seen of me also, as of one born out of due time.” 1 Cor. 15:3-8
“. . . Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.” Acts 16:31
Since what The Lord Jesus Christ did was not just necessary, but fully sufficient, eternal salvation is given freely by grace.
“Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath sent forth to be a propitiation through faith in his blood, . . . ” Romans 3:22-25
“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.” Ephesians 2:8-9
If you have believed on the Lord Jesus Christ, then you can know you have eternal life, that can never be lost. God has promised this in His Word. We have complete assurance of eternal life. Jesus paid the complete penalty for your sin, and His resurrection shows God accepted that payment. This is good news. “And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.” John 10:28 (John 5:24)
Additional important information:
The gospel of Christ is what Christ did for us, not what we do for Christ.. “The Biblical doctrine of redemption and the salvation of man does not lay the burden upon man, but presents man with a finished work which has already been accomplished by God in man’s behalf.” Edmond Gruss
Nowhere does the Bible tell us to “turn from our sins” or “repent of our sins” to be saved. The Greek word translated “repent” in the new testament means “to think differently”, the context tells us what “to think differently” about. The word has no set object. It does not always refer to sin, and is a different word than the Greek word for “turn”. (biblicalrepentance.com)
“The issue in salvation is not what man must do about his sin, but what Christ has already done about man’s sin”. Dr. Charles Bing
The Bible says that Christ died for us while we were yet sinners, and that he saves us as we are. “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;)” Ephesians 2:4-5
Water baptism does not justify us before God, make us “born again” nor wash away sins. The blood that Jesus shed on the cross is what washes us from our sins (Eph. 1:7; Heb. 9:22; 1; Rev. 1:5). “For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; . . .” Rom. 1:16 “For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect. For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.” 1Cor. 1:17-18. “To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.” Acts 10:43
Trying to keep God’s laws and commandments cannot save us. God’s laws (because we have broken them) show us that we are guilty sinners. “Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.” Romans 3:20. “. . . by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.” Acts 13:39
Nowhere in the Bible are we told to “surrender our life”, “give our life”, or make Jesus “lord of our life” in order to be saved.
“We don’t give our hearts, lives, wills, or anything else to God in order to get Him to save us. This would be a form of bribery, a way of meriting or deserving to be saved – but God says salvation is “NOT OFOURSELVES” -and especially, it is not offering anything to God.” Dr. A. Ray Stanford
“But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.” Romans 4:5
