II Chronicles 5:13 It came even to pass, as the trumpeters and singers were as one, to make one sound to be heard in praising and thanking the LORD; and when they lifted up their voice with the trumpets and cymbals and instruments of musick, and praised the LORD, saying, For he is good; for his mercy endureth for ever: that then the house was filled with a cloud, even the house of the LORD;
As they worshipped they recognized God for His character. Please notice with me here in the Old Testament what we see about our God.
He is good. So many think that in the Old Testament He was mean. He is good. He showed love and mercy. He showed kindness. He was willing to make a way to meet with men who had sinned against Him. He is good!
His mercy is forever. He is full of grace and love and it lasts forever. They knew that. You should know that as well. That is why we can have eternal security because we know how He is and how He always has been.
As they worshipped Him for who He really is he blessed their worship by filling the house with His presence in a visible fashion. God is to be loved and worshipped. He is to be honored.
You can not and will not do that until you know more about who He is. He is good. His mercy lasts forever!
