"You, Lord, are forgiving and good, abounding in love to all who call to you." Psalm 86:5
His mercies are new every day, the sun rises and His mercies begin again. He pours them out on us and He never tires. So often we think that God will not pour out any more mercy and that the well is empty. God's well of mercies will never be dry. He cannot tire or giving mercy, He IS mercy.
"The LORD is good to all; he has compassion on all he has made." Psalm 145:9
