Salvation is the deliverance from God’s condemnation and wrath. It is a saving or rescuing from eternal damnation in the lake of fire. It is a saving from being eternally separated from God in this present life and in the life after death.
It is important because man is separated from God.
Now that may not be so important to you, but it is extremely important to God. It may not matter to you that you are not in fellowship with God, but it matters to Him. He cares so much about the fact that man is separated from Him that He provided a way for man to get reconnected to Him.
The way is Jesus Christ. God had Him die on a cross on a hill called Calvary in order to pay the penalty for man’s sin. Jesus Christ gave His life; Jesus Christ died so that man could be rescued, saved, from God’s condemnation and wrath and eternal separation.
This act of death by Jesus Christ brought appeasement of God’s wrath and condemnation toward mankind. God justified this act of Jesus Christ by raising Him from the dead and seating Him at His right hand in heaven bestowing on Him all authority and power in heaven and earth and granting Him the power to give eternal life to all who believe in Him.
This eternal life is re-connection with God. It is living in eternal fellowship with God. It is being forgiven for your sins and becoming a part of the family of God as a son or daughter.
Therefore, God has made a way of salvation for those persons who believe in Jesus Christ and put their faith in Him as Lord and Savior of their lives.
God’s way of rescue from His wrath, condemnation and eternal separation is only through faith in Jesus Christ.
