Who is Jesus? He is the intermediary between us and God:
My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense - Jesus Christ, the Righteous One. He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world. (I John 2:1-2,NIV)
He is not only the sacrifice, but also the priest who presented that sacrifice to God as the atonement for our sins:
First he said, "Sacrifices and offerings, burnt offerings and sin offerings you did not desire, nor were you pleased with them" (although the law required them to be made). Then he said, "Here I am, I have come to do your will." He sets aside the first to establish the second. And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all.
Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God. Since that time he waits for his enemies to be made his footstool, because by one sacrifice he has made perfect forever those who are beig made holy. (Hebrews 10:8-14,NIV)
He is, of course, the atoning sacrifice, whose blood has made it possible for God to grant us as a gift the righteousness which we could never have earned as a salary:
Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God. Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin.
But now a righteousness from God, apart from law, has been made known, to which the Law and the Prophets testify. This righteousness from God comes through faith in Jesus Christ to all who believe. There is no difference, for all have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that came by Christ Jesus. God presented him as a sacrifice of atonement, through faith in his blood. He did this to demonstrate his justice, because in his forbearance he had left the sins committed beforehand unpunished - he did it to demonstrate his justice at the present time, so as to be just and the one who justifies those who have faith in Jesus. (Romans 3:19-26,NIV)
He is the first to be resurrected, and by this resurrection he has conquered death itself. He also reigns for the present, and will continue to reign until death has been totally destroyed. Following The End of Days he himself will be made subject to God the Father:
But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep. For since death came through a man, the resurrection of the dead comes also through a man. For as in Adam all die, so in Christ all will be made alive. But each in his own turn: Christ, the firstfruits; then, when he comes, those who belong to him. Then the end will come, when he hands over the kingdom to God the Father after he has destroyed all dominion, authority and power. For he must reign until he has put all his enemies under his feet. The last enemy to be destroyed is death. For he "has put everything under his feet." Now when it says that "everything" has been put under him, it is clear that this does not include God himself, who put everything under Christ. When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all. (I Corinthians 15:20-28,NIV)
The God we worship is the same God who spoke with Abraham, Isaac and Jacob. He sent his Son, Jesus Christ, among us, so that we would be able to comprehend him more fully through our witnessing his Son's actions and hearing his teachings. He also had his own Son be the perfect sacrifice of atonement, and thus closed the chasm between our shortcomings and his demand for righteousness.
So we worship God the Father as the architect who drew up the blueprints for our salvation. We worship his Son, Jesus Christ, for being the totally obedient Son of God the Father, and therefore the perfect sacrifice that cleanses all mankind of its sins. And we worship the Holy Spirit, who is always with us so as to direct us, guide us, and even scold us when we 'screw up'.
