The word salvation comes from the Greek word soteria, which means "deliverance", preservation and safety." It primarily involves deliverance from the bondage of sin (Galatians 5:1), but also includes deliverance from enemies, (Luke 1:71) and from sickness and disease (Isaiah 53:4 AMP; Matthew 8:17; 1 Peter 2:24).
Salvation cannot be earned through good deeds or by simply being a "good person" (Ephesians 2:8-9). It is a matter of faith (acting out on what you believe according to God's Word concerning salvation). Furthermore, salvation involves a process that will not only guarantee you entrance into heaven, but will also position you to experience a complete life on earth.
Salvation is a gift made available to those who:
(Acts 16:31; Romans 10:9-10).
The word repentance or repent is often identified with sin/wrongdoing. Many understand this term to mean “turning from sin”. This is not the biblical definition of repentance. In the Bible, the word repent means “to change one’s mind.” True repentance will result in a change of actions (Luke 3:8-14, Acts 3:19). Acts 26:20 declares, “I preached that they should repent and turn to God and prove their repentance by their deeds.” The full biblical definition of repentance is a change of mind that results in a change of action.
Many think they are saved because they “believe,” with little or no restrictions on what they believe. Some think it’s enough to “believe in god” some concept of a supreme being or some “force” that operates the universe.
Without faith it is impossible to please God. We must believe that he is. It’s not enough to believe that there was or has been a god who created the universe or “God is dead”. We must believe in his continued existence; God is.
To be saved, we must believe in Jesus; believe he is the Son of God, God in the flesh, did miracles, died as the sacrifice to save us from our sins, and arose from the dead.
When people think of “confession,” they usually think about admitting guilt, which is unpleasant to do. But throughout scriptures we are encourage to confess our faith. Belief in your heart comes before confession with your mouth. What you believe in your heart, you must confess with your mouth. The gospel is gospel not when it is believed but when it is confessed.
"For it is with your heart that you believe and are justified." Justification does not come from the opinions of others. It comes from a heart that believes Jesus Christ arose from the dead and thus "justified freely forever." With your heart you believe and are justified, and with your mouth you confess and are saved. Though confession begins with sin, it doesn't end there. It goes on to confess, "Jesus is Lord." It is good to be a Christian and know it; it's even better to be a Christian and show it. "Let the redeemed of the Lord say so" (Psalm 107:2).
