How often have you noticed a kid at a birthday party asking for more sweets, but if you look closely you notice they already have a handful? Of course we are not going to give them more sweets at that moment, are we?
Sometimes we may not receive what we ask for (from God) because we come bringing our hands "stuffed" with other things - good and bad. It is not that God doesn't want to give us good things, but we aren't able to receive it yet or perhaps even appreciate it.
God gives where he finds empty hands - Augustine
Come to God today in prayer...
"Empty hands held high, such small sacrifice" (Casting Crowns)
