Why was columbus more confident than others about his ability to sail westward?

The main reason why Christopher Columbus was more confident than others about his ability to sail westward because he has an explicit faith that he was called by God for the task of bringing the Christian religion to remote peoples of the word. He believed that God gave him the faith and afterwards the courage to do his task. He has often been hailed as a man of heroism and bravery and faith. Additionally, he sailed westward into mostly unknown waters and his unique scheme is often viewed as ingenious. He set example for us all by showing what monumental feats can be accomplished through perseverance and faith.
