Romans 10:9-10

Because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
For with the heart one believes and is justified, and with the mouth one confesses and is saved.

What an exciting verse because it tells us the simplicity of Salvation. Salvation is based not on our own works but on the work of Jesus. We merely have to acknowledge (confess) Him as Lord and believe in his resurrection and we will be saved. It couldn’t be any simplier than that.
So why the confession of Jesus as Lord? This part of Salvation is essential because it is the basis for justification. Jesus is God, and as such He never sinned. He was perfect. He did not have the sin nature that we have, but was completely perfect. Hebrews 4:15 tells us that Jesus was tempted just like we are, yet without sin.

Hebrews 4:15 – For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin.

This is important because without sin Jesus did not deserve to die. Remember that death is a punishment for sin. Everybody dies because everybody sins. Jesus did not deserve to die, but God put the price for our sin on Him. II Corinthians 5:21 shows us that God put the price of our sin on Him.

2 Corinthians 5:21 – For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.

Jesus, the perfect son of God, paid the price for my sin, and God raised Him from the dead to show His acceptance of this sacrifice. God has justified me by accepting the sacrifice of Jesus death at Calvary, and offers this substitution to all of us if we accept Jesus for who He is, and believe on His name.
With the heart we believe, and with our mouth we confess to salvation. Go tell somebody the Good News of the Gospel today.
