We are to do all those things which Jesus did. If Jesus made people whole, we are called to do the same. If we fail to bring wholeness and faith, we have failed in what Christ told us to do. It's sobering, and it's exhilarating. Jesus told Thomas that there are different roads to faith.
Some people come to faith because they see.
Some people come to faith and are blessed because they hear. Some people come to faith through feeling and knowing the Holy Spirit in their hearts. Some people feel Christ present in the midst of them. The Presence in the midst. On Easter morning, Jesus loved Mary.
