"...if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved." (Romans 10:9)
Jesus died to save man from sin, but salvation from sin wasn't enough. We were free from sin and its consequences, but we weren't free from the power of sin. The resurrection of Jesus gave us a new life and power over sin. This means that the power to live ABOVE sin came as a result of the resurrection-- we were brought into a new life of righteousness!
This is why it's vital that we understand that true salvation is based on our faith in the death, burial, and resurrection of Jesus Christ. If anyone believes in the death but doesn't believe in the resurrection, their salvation isn't complete because it's the resurrection that gives us eternal life.
We read in our opening verse, "...if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved." Verse 10 continues:
"For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation."
From this, we see two things that are involved in salvation: you must (1) confess with your mouth that Jesus is the Lord of your life, and (2) believe that God raised Him from the dead. When a man fulfills both of these things, he can then declare, "I'm saved!" With that, he's immediately ushered into a new life-- one of righteousness, with power over sin.
If you've never been born again, this is what you need: declare that Jesus is the Lord of your life, believing in your heart that He died for you, and that God raised Him from the dead for your justification. If you made that decision today, let us know, we would love to pray with you!
I pray for souls around the world today, that their hearts be open to receive the Gospel as the Word is brought to them through diverse means. The veil is removed from their hearts, and the light of the glorious Gospel shines through, in Jesus' Name. Amen.
