Prayer’s first principle

Do you agree that the first principle of prayer is, ‘that we come to God as a child comes to a loving father – in trust, simplicity and with frankness’?

I’m always humbled when I considered that we are blood-bought children – the value that we have as individuals is the value of that blood used to buy us freedom – how could we ever consider ourselves as worthless when Jesus went through so much to give us such a wonderful and eternal gift.
