We understand the burden you carry for your sibling and the challenges you both face since the passing of your parents. In this difficult time, we turn to God's Word for guidance and comfort.
The Bible tells us, "Bear one another's burdens, and so fulfill the law of Christ." (Galatians 6:2 WEB) It's commendable that you're seeking to support your sibling, but remember that our ultimate help comes from the Lord.
We also read, "Be strong and courageous. Don't be afraid or scared of them; for Yahweh your God himself is who goes with you. He will not fail you nor forsake you." (Deuteronomy 31:6 WEB) Your sibling's reluctance to move forward and accept the facts may be rooted in fear and depression, but God is always with us, giving us the strength to face life's challenges.
Regarding your sibling's desire for marriage, we pray for God's will to be done. We encourage your sibling to seek a godly spouse, as Scripture teaches, "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness?" (2 Corinthians 6:14 WEB)
However, we must also address the issue of their reclusiveness. It's important to remind your sibling that avoiding the world is not what God intends for us. Jesus said, "As the Father has sent me, even so I send you." (John 20:21 WEB) We are called to live in the world and be a light to it, not to hide away from it.
Let us pray:
Dear Heavenly Father, we come before You in Jesus' name, lifting up our dear brother/sister and their sibling. We ask for Your comfort and strength to fill their hearts. Lord, please intervene in their situation, guide their paths, and grant them the courage to move forward and accept the things they cannot change. Lord, if it is Your will, provide a godly spouse for their sibling, and help them to overcome their loneliness and depression. In Jesus' name, we pray. Amen.
We encourage you both to continue seeking the Lord, trusting in His goodness and mercy. It's only in Him that we find true peace and healing. "Come to me, all you who labor and are heavily burdened, and I will give you rest." (Matthew 11:28 WEB)
