Do You Believe Jesus Words?

Do we believe Jesus words?  I think most practicing Catholics would say “yes, of course, we do.”  Then they may cite Jesus’ words to Peter in Matthew 16:18, “And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it.”  Or, they might cite Jesus’ words about the Eucharist in John chapter 6:53, “unless you eat the flesh of the son of man, and drink his blood you have no life within you.”  While we may struggle at times, for the most part, we get Jesus teachings about the Church and the sacraments. That is where most of our minds jump when asked, “Do you believe Jesus words?”  But what about the things Jesus said about you? What about Jesus words about the life we are called to in him? What about the things Jesus said about the Holy Spirit? Do you believe those words? I’ll give you and example. At the end of Mark’s Gospel Jesus says to the disciples, 

These signs will accompany those who believe: in my name they will drive out demons, they will speak new languages. They will pick up serpents with their hands, and if they drink any deadly thing, it will not harm them. They will lay hands on the sick, and they will recover (Mark 16:17-18)
