How should I approach God for help?

Seeking help from God for ourselves, first and foremost, we need to believe that it is his will to see everyone living life wabundantly who comes to him. We must expect it to happen. The sum ‘our faith minus our doubts’ has to leave us with a ‘mustard seed’ sized faith that his love and compassion and help is for us before we are in a place to begin to receive. Then we need the persistence and the humility to reach out for him, and to keep reaching out, until we receive what he has for us. We need to walk humbly with him, putting aside our questions and our criticisms of any abuses we may have seen, and fall on our faces before the Lord.
Secondly, we need to know and believe ourselves to be in the presence of God, not Merely giving credence to a theological concept but because we are aware of the awesome and almost tangible nature of his presence with us.
In the presence of God, how does one pray? How do we even open our mouths? The awesome presence of God is such that we can do nothing but worship him.

So do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ For the pagans run after all these things, and your heavenly
Father knows that you need them. But seek first his kingdom and his righteousness, and all these things will be given to you as well.
Matthew 6:31–33

How should we approach God? With expectant and child–like hearts, as out of our mouths comes worship, thanksgiving and praise.
