God is one being in a Trinity. The Father, The Son (Jesus) and The Holy Spirit are all one. The Son has the same power and will as The Father and The Holy Spirit: that is why they are one God, and the three of them cannot be apart in anyway. The Father & the Holy Spirit sent The Son to pay the price of our sins. By acceptance of the Son. God sent Jesus to earth for our sins.

"So, I need to be saved from what, and why? Believing in God and The Bible is crucial to understanding "What is a savior?" and "Why be saved?" The Bible is God's revealed word to mankind,

Sin is any act that displeases God, as sin separates us from God, who is perfect, such that the payment we are to pay for sin is spiritual death -- permanent separation from God. Romans 6:23: "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord."

Spiritual Death entered into the world when Adam sinned. Genesis 2:17: "But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eat thereof thou shalt surely die." Romans 5:12: "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"

Because we are all born sinful, we are unable by our own whimsical or very deep reason--or in our own strength and morality-to please a perfect God. However, God sent His son Jesus as your representative and as your ransom from being captive.

John 3:16-17 (NIV): "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him."

This belief is trust and faith that God is who He says He is. He provided the payment for our sin by His own son’s taking our place as a substitute. All sins, past, present and future were forgiven by Christ at the cross, although men condemned Him who knew no sin to a cruel, physical death. Hebrews 10:10: "And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all."

Admit that you have sinned. It is a prerequisite to accepting Christ. Once you understand that we are and you are a sinner and that all have sinned, turn to the Lord Jesus Christ for forgiveness by repenting of your sins.

Profess Jesus as your savior. Romans 10:13, "For whosoever shall call upon the name of the Lord shall be saved." Say, "Father in Heaven, I believe that Jesus died for my sins." And God will impart eternal life to your spirit.
