In this sermon, we explore Jesus' teachings on sexual purity and the importance of guarding both our hearts and actions. Drawing from Matthew 5:27-30, we see that sin begins in the heart, and Jesus calls us to take extreme measures to fight it. God's design for sex is within the covenant of marriage (Genesis 2:24), and He is serious about both our earthly and spiritual covenants (Ephesians 5:31-32). As believers, we're called to pursue holiness in our relationships—seeking our Savior first and honoring our marriage vows.
