Why do Jehovah's Witness not consider Jesus to be God when St. Paul says He is the Savior?

Given the scripture which says: > But what does it say? "The Word is near you, in your mouth and in your heart--that is, the word of faith which we are preaching, that if you confess with your mouth Jesus as Lord and believe in your heart that God raised Him from the dead, you shall be saved. for with the heart man believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation. For the Scriptures says, "Whoever believes in Him will not be disappointed. For there is no distinction between Jew and Greek; for THE SAME LORD is Lord of all, abounding in riches for all who call upon Him; for "Whoever will call upon the name of the Lord will be saved." > > Romans 10:8-13 and > to the church of God which is at Corinth, to those who have been sanctified in Christ Jesus, saints by calling, with all who in every place call upon the name of OUR LORD JESUS CHRIST, their Lord and ours. > > 1 Corinthians 1:2, Since Jehovah's Witnesses explicitly teach that Jesus Christ is "a god" who was created, on what basis is he able to save billions of people by calling upon "a god"? How can you claim that you are saved by way of "a god"?
