Larry Montgomery, director of Team Ministries at GO InterNational, emphasizes that the call to global missions is for every believer. God's mission is global, as seen in His covenant with Abraham and the Great Commission in Matthew 28:19-20. The church plays a crucial role in sending and supporting missionaries. Believers can get involved by praying, supporting missionaries, going on mission trips, considering long-term service, and engaging locally with a global vision. Aligning our hearts with God's will and taking practical steps can help fulfill His mission for the nations.
