Introduction to the sermon series What is the difference between Christians in this generation and the heroes of faith that we have in the Bible?  What is the difference between Abraham and us?  What would make a man leave all his family, leave all comfort and go to a place that He does not know, just because God told him?  What would make the disciples leave their livelihoods and follow Jesus? What would make Joseph trust in God and live in obedience to Him even though he was sold into slavery and sent to prison at God’s watch? What would make Hosea marry a prostitute? What would make Isaiah prophecy naked for 3 years? What would make Paul go through all that he went through to preach the gospel to Gentiles? What would make these men and women to be totally sold out to God even at a huge cost to themselves? What would make people do anything for God? What would make people love God with all their hearts? These people were convinced of several things and that is what we will be discussing this month in our sermon series. We have titled the sermon series ‘Are you convinced?’ Today’s sermon is titled:  Are you convinced that Yahweh is God?
