We know God comforts us through His promises and our experiences of His presence in times of trouble.
The assurance that God comforts us in our troubles comes from both Scripture and personal experience. In John 14:18, Jesus promises, 'I will not leave you comfortless: I will come to you.' This shows that God actively seeks to provide encouragement and consolation to His people. Furthermore, the Apostle Paul writes about his own experiences of affliction, detailing how God comforted him so he could comfort others (2 Corinthians 1:4). Christians can rely on this promise as they endure their own tribulations, knowing that God has not abandoned them but is intimately aware of their suffering and is present to provide comfort and strength.
