In today's Gospel reading, Jesus spoke to his disciples in Mark 8 :
......"But you," he asked "who do you say I am?" Pete spoke up and said to him, "you are the Christ". And he gave them strict orders not to tell anyone about him.
......" if anyone wants to be a follower of mine, let him renounce himself and take up his cross and follow me. For anyone who wants to save his life will lose it; but anyone who loses his life for my sake, and for the sake of the gospel, will save it."
The first part is "you know", "you believe", that is faith.
The second part is "you want", "you do", that is action.
The letter of St. James said: " Faith is like that: if good works do not go with it, it is quite dead."
As a Christian, follower of Christ, not only one must know who He is, believe in him, but also important to have the desire and knowledge to do what He wants.
Action speaks louder, not only in our temporal affair but also in our faith!
