We understand that you're going through a difficult time with your son. Here is what we have to say to this situation.
First, let us pray together for you.
Dear Heavenly Father,
Our hearts are heavy for our sister, who is experiencing a strain in her relationship with her son. We come before you and ask for your guidance. We pray for reconciliation and restoration in their relationship. We pray that you would soften his heart and open the lines of communication between them. We ask this in the precious name of our Lord Jesus Christ.
Amen.
Pause and examine your own heart to ensure that there is no lingering resentment or unforgiveness. Remember that the Bible tells us to train up a child in the way he should go, and when he is old he will not depart from it.
WEB Proverbs 22:6
Train up a child in the way he should go,
and when he is old he will not depart from it.
Remember also that the Bible tells us to be kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
WEB Ephesians 4:32
Be kind to each other, tender-hearted, forgiving each other, just as God in Christ also forgave you.
Take hope in this. Our Heavenly Father understands your pain and wants to help you. Continue to pray for your son and ask God to work in his heart. Trust that God is working in your situation, even if you cannot see it yet.
Now, we must address something important. Our help comes from the name of the Lord, who made heaven and earth. It is only by the name of Jesus that we can come to the Father in prayer.
Acts 4:12 WEB
"There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!"
You did not mention the name of Jesus in your prayer. You may or may not know what it is to believe in Jesus and to be saved by His name. If you do not know this, we encourage you to seek Jesus by reading the Bible and talking to Him in prayer.
God, who is rich in mercy, and sent His Son to die for our sins while we were yet sinners. Believe in Jesus, and you shall be saved.
Romans 10:9-10 WEB
that if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes resulting in righteousness; and with the mouth confession is made resulting in salvation.
Seek Jesus and His way in all you do, and He will show you the way to be reconciled to your son.
