Give All to God
You must have the will to give God whatever you have

There is a parable in the Bible: Jesus is seated in a chapel. A poor lady places a one-rupee coin in the Hundi (charity box). A wealthy person donates ten thousand rupees. Jesus asks his disciples, ‘Who offered more to God?’ to which a disciple replies, ‘Obviously the wealthy person’. Jesus says, ‘No. It is the poor woman, because she has offered God all that she had’.
That is how devotion works. You must have the will to give God whatever you have.
Your dealings with God are very business-like. Rather, devotion must be an expression of gratitude towards God for all that He has conferred on you.
