Jesus also tells us more that we must do...

Matthew 10:32 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.

We must "confess" Jesus before other men... we cannot be ashamed of Jesus nor can we be ashamed of His words...

Luke 9:23-26 Then he said to all of them, "If anyone wants to come with me, he must deny himself, pick up his cross every day, and follow me continually. For whoever wants to save his life will lose it, but whoever loses his life for my sake will save it. What profit will a person have if he gains the whole world, but destroys himself or is lost? If anyone is ashamed of me and my words, the Son of Man will be ashamed of him when he comes in his glory and the glory of the Father and the holy angels.

In the following passage, the apostle Paul confirms what Jesus taught concerning believing and confessing...

Romans 10:9 If you declare with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. (ISV)

Romans 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. (KJV)

It is certainly clear that if do not "confess with our mouth that Jesus is Lord", and "before men", then Jesus will not confess us before His Father (God).

We can read of a good example of how we confess within the story of the apostle Phillip and the eunuch...

Acts 8:35-38 Then Philip opened his mouth, and beginning from this scripture he preached Jesus to him. As they went along the road they came to some water; and the eunuch said, "Look! Water! What prevents me from being baptized?" And Philip said, "If you believe with all your heart, you may." And he answered and said, "I believe that Jesus Christ is the Son of God." And he ordered the chariot to stop; and they both went down into the water, Philip as well as the eunuch, and he baptized him.

After Phillip preached Jesus to the eunuch and as they were traveling down the road, notice the first words the eunuch spoke... "Look! Water! What prevents me from being baptized?"

It appears the eunuch was overjoyed that he could obey and be baptized. Phillip explained to him that nothing would hinder him as long as he believed with all of his heart.

Now notice how the eunuch confessed Jesus as he answered Phillip... "I believe that Jesus Christ is the Son of God." Then the eunuch was immediately baptized.

The eunuch heard the gospel, he believed it, he confessed Jesus, and he was baptized.

The eunuch made the "good confession" which Jesus testified of and Paul confirmed...

1 Timothy 6:12-13 Fight the good fight of faith; take hold of the eternal life to which you were called, and you made the good confession in the presence of many witnesses. I charge you in the presence of God, who gives life to all things, and of Christ Jesus, who testified the good confession before Pontius Pilate,

In order for us to abide in God we must "confess" Jesus in the Son of God...

1 John 4:15 Whoever confesses that Jesus is the Son of God, God abides in him, and he in God.

Now it becomes even more clear that "believing He exists" cannot be all we have to do.

We have "learned" thus far that we must "hear the gospel of Christ" and we must "believe in Him" and we must "repent of our old ways of sin and turn to God" and we must "confess Jesus is the Son of God".
