Spiritual growth requires both deep roots in Christ and active outreach to others. Like plants need strong roots to thrive, our faith needs to be firmly established in Jesus to bear fruit. This involves a two-directional approach: reaching up to God through worship, prayer, and Bible study, and reaching out to others by sharing our faith. Our personal testimony is a powerful tool that doesn't require theological expertise—just authenticity about what Jesus has done in our lives. When we understand God's heart for the lost as illustrated in Luke 15, we're motivated to fulfill the Great Commission by investing in relationships and helping others take steps toward Jesus.
