Pastor Jon Gaus delivers a sermon titled "Make it Personal," focusing on discovering Jesus in the Old Testament and applying biblical truths to daily life. By comparing the complexity of the Old Testament to "Where's Waldo?", he explains how knowing what Jesus looks like helps us find Him throughout Scripture. Examples like Abraham's sacrifice of Isaac in Genesis 22 and Nehemiah's role as a precursor to the Messiah highlight Jesus' presence in the Old Testament. The sermon concludes by urging believers to daily walk in the Spirit, avoid comparisons, and commit to God's way of escape to fully embrace their new identity in Christ.
