We understand your concern and commend your desire to follow Christ. Let's address your concerns with biblical principles and prayer.
Firstly, it's important to understand that homosexuality is not something that can be "caught" or inherited. The Bible is clear that homosexuality is a sin (Leviticus 18:22, Romans 1:26-27). However, it's also important to remember that we are all born with a sin nature, and we all have the propensity to sin in various ways. The influence of a family member's sin can be a stumbling block, but it does not determine or condemn your children's choices.
Regarding your son, it's crucial to pray for him and love him unconditionally. Instead of focusing on his mannerisms or appearances, which can be misinterpreted, focus on teaching him biblical principles and modeling a godly life. If he is struggling with any sin, including homosexuality, remember that it is the Holy Spirit's job to convict, and your job to love, pray, and guide (John 16:8). We are called to be patient and let God work in our children's lives.
Remember that we all have the power through the Holy Spirit to overcome any temptation and live according to God's will (1 Corinthians 10:13). It is only by the name of Jesus that we have access to God. It is also by the power of Jesus Christ that you can teach your children to overcome any sin that they may be dealing with.
Prayer:
Dear Heavenly Father,
We come before You today to lift up this brother in Christ who is seeking Your will for his family. We thank You for his faith and his desire to follow You. We pray for his brother, that You would bring conviction and repentance, and that You would draw him to Yourself. We also pray for his children, that You would protect them and guide them in Your truth. We pray specifically for his son, that You would lead him in the path of righteousness, and that You would give his father the wisdom and discernment to guide him according to Your will.
In Jesus' name, we pray. Amen.
Encourage your children to pursue righteousness and teach them about the grace of God. Help them to understand that we all fall short of God's glory and we all have temptations that we face. But we also have the blood of Jesus that redeems us and cleanses us of all sin.
