It is important to understand what is scripturally meant by “born again” and “being saved.”
BORN AGAIN
The phrase “born again” is found in John 3:3. “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” A more accurate translation for “born again” is “begotten from above.” It does not describe a second birth. It refers to the changed relationship with God when the power and influence of His holy spirit is given to us.
Being begotten from above is a process of our spiritual development: God first calls us to follow Jesus. If we accept the call the next step is to dedicate, or consecrate, our lives to doing God’s will. God then “begets” us with His holy spirit.
The term “begets” is taken from the natural birth process where a life is first conceived (or begotten) and after growth and development is finally born. A faithful Christian’s life is similar to this natural process. Receiving the holy spirit is the begettal part. We are now considered “sons of God” as described in 1 John 3:2: “Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.”
Our spiritual growth and maturity as Christians is compared to a gestation period. Finally, after a life of devoted service to God and growth in the image of Christ, we are “born” as spirit beings.
Spiritual growth and birth are described by the Apostle Paul in Romans 2:7: “To them who by patient continuance in well doing (the growth) seek for glory, honor and immortality, eternal life (the birth).”
So, when Jesus said we must be born again, he meant that a life of faithfulness to God would result in a heavenly reward and a spirit birth.
BEING SAVED
Being saved not only describes the process a Christian experiences but also has an application to mankind. That aspect is alluded to in 1 Corinthians 15:22: “For as in Adam ALL die, even so in Christ shall ALL be made alive.” Being saved is not limited to Christians who live in this age. The purpose of the coming Millennium will be to raise mankind from the dead and give them a full opportunity to believe and dedicate themselves to God. The scriptures indicate that mankind will be given 1,000 years to grow and development without the influence of Satan or corrupt worldly influences (See Revelation 20:1-4).
This process for the world is mentioned in 1 Timothy 2:3-6: “For this is good and acceptable in the sight of God our Savior; who will have all men to be saved, and to come unto the knowledge of the truth. For there is one God, and one mediator between God and men, the man Christ Jesus; who gave himself a ransom for all, to be testified in due time.”  In the coming age, Jesus will act as the mediator between God and mankind. He (and his faithful followers of this age) will teach the world to love righteousness and consecrate their lives to God.
The word “ransom” can also be translated “corresponding price.” This shows us that the sacrifice of Jesus’ life was a corresponding price for Adam as described in 1 Corinthians 15:22. It describes a one-for one exchange: the life of Jesus for the life of Adam. By purchasing Adam, the father of mankind, Jesus then also purchased the entire race. This gives him the authority to resurrect all the descendants of Adam.
Remember then, that being “begotten from above” describes the work of the holy spirit in the life of a Christian. “Being saved” describes the greater work of saving not only Christians but the entire world. These comprise the two ages of salvation.
