My friend Jim gets up early every morning, and gets dressed with a white shirt, a suit and tie. And he's done this for 60 years.

Of course it's a habit, but it's a habit that's rooted very deeply in his understanding of who he is and what he is on Earth to do.

"I spent my life in business, and I think if a person wants to be taken seriously, they need to look the part," he once told me.

Now I'm not sure if Jim's dress code is a result of his confidence or if his confidence is a result of his dress code, but either way I've always been envious about Jim's close connection with his purpose.

And this is what lies at the heart of our Gospel on Sunday, this is when you and I will hear the familiar story of Jesus calling his disciples. He will perform a miracle with a couple of fishermen and Peter will be so impressed that he'll fall at Jesus's feet and declare that he is not worthy to be in his presence.

In doing this, Peter will tap into our own feelings of inadequacy.

Who are we to be called by God? - to start a business, be a parent, wear nicer clothes, or speak up for the vulnerable?

We, like Peter, are programmed to always undervalue ourselves and overvalue others.

What we can find here is that a lack of self-worth and significance is related to our understanding and ownership of our purpose: our feelings of inadequacy are related to our disconnection with purpose.

So Jesus responds to Peter by telling him not to be afraid and to come and embrace his purpose - to be a fisher of men, to live a life rooted and grounded in God and in God's call and purpose, which only Peter will be able to fulfill.

To get nearer to Jesus means to get nearer to ourselves, to who we are, and what we're called to do. And it is Peter's example of taking Jesus's hand, amidst his fear, his poor self image, and his doubt, and following.

When we follow Jesus, when we move to order our paths after God, when we make our pursuit of God our first priority, and walk in the confidence that God has called us, equipped us, and is using us to do the work of love in the world, that only we can do, our sense of inadequacy can be greatly diminished.

Jesus' call to St Peter is the same call to you and me, that we put our feelings of poor self-worth and inadequacy aside and look to get busy with what we're called to do.

In what ways is God inviting us to double down on our calling, to take our lives in Christ more seriously, and to engage the purposes for which we've been called?
