In his sermon, Jason discusses how often our Christmas plans go awry and draws parallels to the unexpected circumstances surrounding Mary’s miraculous pregnancy. He emphasizes that when God changes our plans, we can either embrace this change in faith or reject it in fear, highlighting the beauty of God’s purpose over our expectations. Jason elaborates on how God’s invitations often come at inconvenient times and may lead us to experience discomfort but ultimately guide us to something greater. He encourages us to trust in God's plan, noting that while our responsibility is to obey, the outcomes rest with Him.
