21.Who sings praises to God in the midst of the church?

Christ. When we sing hymns to God and praise God, Christ sings with us, His brothers. As we all sing praises there is satisfaction in the heart of God.

I will declare thy name unto my brethren: in the midst of the congregation will I praise thee (Psalms 22:22).

And I will wait upon the Lord, that hideth his face from the house of Jacob, and I will look for him. Behold, I and the children whom the Lord hath given me are for signs and for wonders in Israel from the Lord of hosts, which dwelleth in mount Zion (Isaiah 8:17,18).

Christ trusts in the Father; and we, whom God has given to Christ, also put our trust in the Father.
