Now to him who is able to do far more abundantly than all that we ask or think, according to the power at work within us. Paul praises a God whose possibilities far exceed our imagination.
In the New Covenant, provision is not limited by your lack or your imagination. God's power works IN you, not just FOR you. You are not a beggar at his door but a son in his house.
Today you may think generously. Not because you are presumptuous but because your Father is abundant.
