It's hard to believe that we're already through the first month of the year, yet this Sunday will be the first Sunday in February! Being the first Sunday of the month, we will be observing the sacrament of the Lord's Supper, so Pastor John will be taking a break from our series on 1 & 2 Thessalonians and will be preaching instead from the book of Exodus. We will be looking at God's provision for the Israelites in the desert, and our call to remember God's provision for us in Christ.
For our Song of Ascent, we will be singing the hymn "Holy, Holy, Holy." I thought it would be good to begin the service with one of the great Trinitarian hymns of the faith that declares God to be holy and sovereign over all things . And as the hymn says, "though the darkness hide thee," we can still know and trust God to be who He has revealed to us in His Word. The hymn says that "all thy works shall praise thy name," and so, those who believe and trust on God and His provision, sing as we gather, in Christ, to worship Him.
For our Hymn of Praise, we will be singing our psalm for the week, which will be the same selection as will be read for the Old Testament reading. It is the same story that will be in this week's sermon, but from a psalmist's perspective. We will sing of how the Israelites left Egypt and were provided for by God in the desert. 
For our Hymn of Rejoicing, I chose one of my personal favorites, "Before the Throne of God Above." This is one that comes to my mind whenever I think about remembering God's perfect provision in Christ for my sinful nature. It reminds us that even "when Satan tempts me to despair" we can look to God "who made an end of all my sin." As a Hymn of Rejoicing, it is perfect because the entire hymn is one of thanksgiving to God for redemption.
