How do we know Christ's promise to be with us is true?

The truthfulness of Christ's promise to be with us is rooted in His divine nature and the testimonies of Scripture. Jesus, who declared, 'All power is given unto me in heaven and in earth' (Matthew 28:18), possesses the authority to fulfill His promises. Throughout the Bible, we see consistent evidence of His faithfulness. For instance, in Isaiah 54:10, He promises, 'For the mountains may depart and the hills be removed, but my kindness shall not depart from you.' This steadfast commitment assures us that His presence will never waver, providing believers with the confidence that He is always with them, especially during life's most challenging moments.
