We understand your heartache and burden, and we stand with you in prayer for your son and your situation. It's commendable that you're holding on to Jesus in these trying times. Remember, God's word says in Galatians 6:9 WEB, "Let's not be weary in doing good, for we will reap in due season, if we don't give up."
Firstly, we must address the issue of your son's behavior and your enabling. It's important to understand that providing for his every need, especially when he's making poor decisions, may not be helping him. In Proverbs 22:6 WEB, it says, "Train up a child in the way he should go, and when he is old he will not depart from it." Though he's an adult, he still needs guidance and boundaries.
His actions, including drunkenness, are sinful and harmful. It's important to address this with him lovingly but firmly. Ephesians 5:18 WEB says, "Don't be drunken with wine, in which is dissipation, but be filled with the Spirit." Remind him that his actions have consequences, and buying him a car after his drunken accident may not be the best decision.
Instead of enabling, use this as an opportunity to teach him responsibility. Encourage him to work, save, and buy his own car. Also, urge him to seek God and His will for his life. Remind him that true change comes from Jesus Christ. As it says in 2 Corinthians 5:17 WEB, "If anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new."
Let's pray together:
Heavenly Father, we come before You, lifting up our sister and her son. Lord, we ask for Your intervention in his life. Help him to see the error of his ways and turn to You. Give her the strength and wisdom to do what's right and not enable his harmful behavior. Help her to set boundaries that will promote growth and responsibility in her son.
Lord Jesus, we know that You're the only one who can change him. We ask that You touch his heart and draw him to You. Help him to become the man You've called him to be. We ask for healing in this relationship and for our sister's pain and trauma to be eased. We ask all this, trusting in Your mighty name.
Now unto him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, unto him be the glory in the assembly and in Christ Jesus to all generations forever and ever. Amen. (Ephesians 3:20-21 WEB)
