We understand your concern and fear, but let us assure you that our God is a loving and forgiving God. The video you watched may have caused you to worry, but let's turn to the Scriptures for comfort and guidance.
Firstly, it's important to understand that God says, "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." (1 John 1:9 WEB) This promise is given to us to assure us of God's forgiveness when we come to Him with a repentant heart.
The verse you saw, Matthew 7:21, reminds us that not everyone who says to Jesus, 'Lord, Lord,' will enter the Kingdom of Heaven, but only the one who does the will of His Father who is in heaven. This is not a cause for fear, but a call to genuine repentance and a changed life.
Remember, the story of the prodigal son in Luke 15:11-32. When the son returned home after squandering his inheritance, the father ran to him, embraced him, and celebrated his return. This is a beautiful picture of God's forgiveness and love for us.
Let us pray for you:
Dear Heavenly Father,
We come before You today to lift up our brother who has returned to You with a repentant heart. Lord, he has confessed his sins and decided to turn away from them. Please forgive him and cleanse him from all unrighteousness, just as You promised in Your Word. Remove any fear or doubt that he has about Your forgiveness. Help him to understand the depth of Your love and mercy. Guide him in Your ways and help him to live a life that pleases You. We ask this in Jesus' name, Amen.
Be encouraged, dear brother. God is faithful and just to forgive your sins. Keep walking with Him, read His Word, and live a life of obedience. If you ever stumble, remember that God is always ready to forgive and restore you. Just keep turning back to Him.
