This easy-to-read website will help you understand God's offer of new life in Jesus Christ. When Jesus came to this earth, He defeated sin by His Cross and He defeated death by His resurrection. There are five essential elements of the "Good News."
You Have Already Been Forgiven
 Forgiven: Your sins have already been forgiven and forgotten by God! Forgiveness was based on Christ's sacrifice, not your response to it. Forgiveness is God's gift of grace to all people (Colossians 1:20; John 1:29; 1 John 2:2). Since the sins of all people for all time were forgiven and forgotten on the Cross of Jesus Christ (2 Corinthians 5:19; Mark 3:28; Hebrews 8:12), you do not need to seek forgiveness from God. The long-standing myth that you must receive the gift of forgiveness by faith* is not found anywhere in the Bible. However, unbelief is still the barrier but the reason is different; unbelief is rejecting the eternal life that is found only in Jesus Christ.
*Note: It is the gift of righteousness, not forgiveness, that you must receive by faith in order to be saved (Romans 5:17).
How You are Saved
 Saved through Faith: All are forgiven but not all are saved. Only when your unbelief is turned to faith in Christ as Savior does God remove your old sinful inner nature and replace it with a brand new, clean heart (Ezekiel 36:26; Romans 6:6).
 Born from Above: With a new heart you become, for the first time, a "clean vessel." You are a brand new person on the inside (2 Corinthians 5:17). God, in all His holiness, now has a place within you where He can live (1 Corinthians 3:16; 6:19). God's Spirit comes to live in your "born again" heart. Having God's life dwelling in you is what it means to be "saved." This is the new life (1 John 5:12; 2 Peter 1:4) that comes only through faith in Jesus Christ. You possess eternal life because Jesus, Himself, is Eternal Life (1 John 5:11; 1 John 1:2), and He now lives in you (Colossians 1:27; 2 Corinthians 13:5).
Note: "God's Spirit living in you" and "Jesus Christ living in you" are both the very same thing (see Romans 8:9, 10a, 11).
Your Life with Christ
 Union with Christ: With Jesus Christ living in you, His presence makes you literally righteous in your born again heart (Ephesians 4:24) because Jesus, the Righteous One, is inseparably joined to you in your new spirit (1 Corinthians 6:17). Righteousness has not merely been credited (imputed) to you, it has been given to you as a gift, and the gift is the person of Jesus Christ (Romans 5:17). You can never, ever sin in your new spirit because Jesus in you can never sin (1 John 3:9). This is why you are secure forever in God's family (Colossians 1:13; 1 Peter 1:23).
 Living by Faith: Your redeemed inner spirit still "lives" inside the same mortal "house" that you had before you were saved. Your physical body has not yet been redeemed; it awaits a future redemption (Romans 8:23b). Unlike your new righteous spirit, your outer mortal body is still dead because of sin (Romans 8:10). You are spiritual perfection living inside mortal imperfection (2 Corinthians 5:2). This is why you can still sin in your mortal flesh.
More important, this is the reason you live by faith. You can never make your mortal flesh righteous because it does not have the capacity to be righteous. Most Christians are taught to live by their own human strength. This has led to the endless try-fail-confess cycle; worse, it creates the culture that minimal sinning is acceptable while a lot of sinning is unacceptable. God's only standard is perfect righteousness.
The only way you can live a life pleasing to God is to bypass your outer, mortal flesh. You do this by living from the power of Christ in you. Jesus lives in your born again spirit, joined as one to you. As you follow Him in faith, you will experience His righteous life being lived in you while He does His good works through you (Galatians 2:20). At the times that you do stumble, simply return to following Christ in faith; feelings of guilt and shame are NOT from God (Romans 8:1).
When Jesus was baptized at the beginning of His earthly ministry, the Holy Spirit came down to dwell in Him. In this way, the Father did His works and miracles through Jesus, as Jesus followed His Father in faith (John 14:10). Jesus did not do these works by His own human strength (John 5:30; 5:19; 8:28). The Good News is that the same Holy Spirit that lived in and empowered Jesus now lives in you! This is why Jesus is both your Savior and your model for the life of faith.
Note: Your "heart," "spirit" and "nature" all mean the same thing. Your inner spirit is the real, "essential," eternal you while your mortal human body is your temporary "tent" (2 Corinthians 5:4; 4:16).
