I will answer them before they even call to me.
    While they are still talking about their needs,
    I will go ahead and answer their prayers! (NLT).

This probably refers to every need being met in the new creation. Nevertheless we do even now have remarkable foretastes of this truth in our own lives, where God meets a need even before we get to articulating it before Him. It is important to pray, but sometimes there can be wonderful answers to prayers not yet prayed.

‘God will anticipate their prayers with the blessings of his goodness. The father of the prodigal met him in his return. God’s readiness to hear prayer appears much more in the grace of the gospel than it did under the law.’ Matthew Henry.
