Paul knew that he could provide the information they were missing and help them be at peace with the passing of fellow followers of Jesus Christ. He said, “I don’t want you to lack knowledge about the coming of Christ, ‘lest you sorrow as others who have no hope.’” Paul was about to drop some knowledge that would give them hope concerning the deceased Christians. In verse 14, he said, "For if we believe that Jesus died and rose again, even so God will bring with Him those who sleep in Jesus."
THE WORD AND THE WITNESS
When we share the Gospel of Jesus Christ, we are engaged in a supernatural act. Neither the message nor the power is our own, and the outcome is not dependent upon our elocution or rhetorical skills. When we open our mouths “to tell the old, old story, of Jesus and His love,” the Holy Spirit empowers us to be witnesses (Ac 1:8). So, we can be sure that God’s word will accomplish what God has purposed, it will not return void (Is 55:11).
Holy Word
The Bible is not a magical book of powers that anyone can recite or chant and expect to see results. The Word of God is powerful in the lives of those who abide in Jesus and live by His words. Jesus said in John 15:7, “If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you.”
