S – At that time he rejoiced in the Holy Spirit and said, “I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and intelligent and revealed them to infants. Yes, Father, because this was your good pleasure.^, 

Luke 10:21 CSB

O –  Commentary: 

Jesus was full of joy through the Holy Spirit. Luke frequently mentioned the Holy Spirit’s ministry in Jesus’ life. The three Persons of the Godhead are clearly seen: Jesus the Son was doing the Father’s will in the power of the Holy Spirit. Each had a specific function (vv. 21–22).

“Luke,” in The Bible Knowledge Commentary: An Exposition of the Scriptures\

A – We can have joy in the Holy Spirit.  I usually refer to the function of the Holy Spirit to help me in my relationship with God.  Yet, I often neglect to ask for his help to have joy or celebrate God.  That is also an important part of the relationship.

R – Lord, I celebrate You today!  You are an infinite God and you love me and everyone else you created.  I exalt you to the highest level and rejoice in You.
