Call to Worship: from Psalm 145:18 and Isaiah 55:6-7

The Lord is near to all who call on him, to all who call on him in truth. Seek the Lord while he may be found; call upon him while he is near; let the wicked forsake his way, and the unrighteous man his thoughts; let him return to the Lord, that he may have compassion on him, and to our God, for he will abundantly pardon.

-from Psalm 145:18 and Isaiah 55:6-7 (ESV)
