The central message of this sermon is that it's okay to question God when He doesn't do what we expect Him to do, as long as our questions come from a place of faith and a desire to follow Him. The sermon emphasizes that even great servants of God like John the Baptist have had deep and disturbing questions about God's ways, but these questions are not a rejection or defiance of God's truth, but rather an honest expression of confusion and frustration. By examining John's question to Jesus ("Are you really the Messiah?"), the sermon highlights how our expectations can be misplaced due to a lack of understanding about God's timing and purposes, particularly in relation to His second coming. The takeaway is that when we have questions for God, it's essential to articulate them clearly and then listen for His answer, which often requires us to trust in His sovereignty and goodness even when we don't understand the details.
