Larry StammLarry Stamm Ministries exists to make the Gospel of Jesus a confident topic of conversation for every Christian.  Our goal is to equip and inspire Christians to press on in fulfilling the Great Commission – Jesus’ command to go and share the good news with all the world. Larry Stamm knows firsthand what it looks like to share the gospel simply, effectively and biblically – just like Jesus did.  Jesus was Jewish. He observed all the feasts of Israel, went to Temple and claimed to fulfill all the Scriptures that foretold his destiny. We provide teaching that connects the dots between the Old and New Testaments through Larry’s unique lens as a Jewish believer in Jesus.  Our ultimate purpose is to strengthen gospel foundations so that Jesus will be glorified and you will gain confidence in witnessing.
