All of Scripture is about the Lord Jesus. Even in the Psalms, we see pictures of the coming Messiah, even in the Christmas spirit. These sermons direct listeners to consider the arrival of Christ as seen in the Old Testament Scriptures of the Psalms.
Does God have a purpose for our lives fulfilled in suffering? Ultimately, God's people will persevere through suffering in an attitude of worship. They will not lose hope, nor turn away from the Lord. In addition, Scripture gives us hope and encouragment in relation to human suffering.
Modern day carolers are not the only ones who get to celebrate the Christmas season in song. Several Biblical characters lift up their worship to the Lord in song in the pages of Scripture.
