The Lord detests the sacrifice of the wicked,
but he prayer of the upright pleases him.
The Lord is far from the wicked,
but he hears the prayer of the righteous.
Proverbs 15:8, 29
What's the difference between the wicked and the righteous? Within the context of the Bible, the main difference is that the wicked refuse to acknowledge God as Lord, the only one in charge, relinquishing their right to be god of their own lives. The righteous/upright have surrendered to Him. That's what enables them to cry out in prayer.
In prayer we are saying, "This life thing is beyond me; be God, God, because I'm not and I can't be!"
It's this surrender that so pleases the Lord! Blessed are those who cry out to the Father - sins are forgiven, life is given, hope is born. He hears your prayers.
May today be prayer-full for you, in the smallest and greatest of tasks!
