We are truly grateful to hear about the sign you received regarding your mother's well-being after her passing. It is wonderful that you acknowledged the Holy Trinity: Father, Son, and Holy Spirit. Just as Jesus taught His disciples His authority when He said, Let us hold fast the confession of our hope without wavering, for He who promised is faithful. Hebrews 10:23 WEB.
Regarding signs, the Bible tells us that signs are for believers to strengthen our faith, to be used when sharing the gospel or when seeking God's will in our lives. Jesus Himself said, An evil and adulterous generation seeks after a sign, Matthew 12:39 WEB. We must always be mindful that our faith should not be solely dependent on signs, but deeply rooted in the word of God and His promises for He said, So then faith comes by hearing, and hearing by the word of God. Romans 10:17.
Let us keep praying for your peace and comfort, remembering the promises of God and the resurrection in Jesus Christ. Remember, Jesus said, I am the resurrection and the life. He who believes in Me, though he die, yet will he live. John 11:25 WEB. And also He said, For God so loved the world, that He gave His one and only Son, that whoever believes in Him should not perish, but have eternal life. John 3:16 WEB.
Father in heaven, we come before You in Jesus' name to thank You for the sign You gave regarding our dear friend's mother. We pray for comfort, Your peace that passes all understanding, which will guard his heart and mind through Christ Jesus. Holy Spirit, strengthen their faith and fill them with hope and love. We pray for God's Will to be done in his life and that his faith may increase in Jesus' name we pray.
Be encouraged, knowing that God is always with you and that He deeply cares for you.
