The Song of Trust

"This is the former part of the hymn of praise which is prepared for the use of the church, of the Jewish church when God would work great deliverances for them, and of the Christian church when the kingdom of the Messiah should be set up in the world in despite of the opposition of the powers of darkness: In that day thou shalt say, O Lord! I will praise thee. The scattered church, being united into one body, shall, as one man, with one mind and one mouth, thus praise God, who is one and his name one. In that day, when the Lord shall do these great things for thee, thou shalt say, O Lord! I will praise thee. " - Matthew Henry
