This sermon explores the connection between our hearts and our finances, using Matthew 6:19-21 as the foundation. Pastor Mark emphasizes that where we put our treasure, our hearts will follow - not the other way around. He explains that God desires our whole heart, and one key indicator of whether God has our heart is the position He holds in our finances. The message focuses on tithing as a biblical principle that helps align our hearts with God's priorities, explaining that the tithe is 10% of our income given first to God through the local church. The sermon addresses common objections and emphasizes that this isn't about legalism but about heart posture and trust in God's provision.
