God should be the most important thing in your life and if you loved your kids half as much you would know that standing firm in your love of Jesus is loving them.
Jesus was offensive. Most people were offended by him. The proof for John the Baptist that Jesus was the Christ was that the blind see, the lame walk and the majority are "offended" by Him (Mat. 11:2-19). As Jesus said, "Blessed is he who is not offended because of Me" (Mat. 11:6; Luke 7:23).
If your stance for Jesus offends them, so be it.
In Galilee, Jesus did not plead with his neighbors to understand Him when "they were offended at Him" (Mat. 13:57; Mark 6:3). If unbelievers are offended, so be it (cf. Luke 14:3-4; John 5:8-16). "Shake off the dust from your feet" (Mat. 10:14). But alas, that is no longer a Christian attitude it seems...
Christ’s apostles asked Him, "Do you know that the Pharisees were offended when they heard [Your] saying?" (Mat. 15:12). What is the accepted Christian response today after an offense is taken? Quick, apologize! Ask for forgiveness! Tell them you are sorry. How did Jesus respond? He said to ignore the complaints of the unbelievers: "Let them alone. They are blind," (Mat. 15:14). Today, many Christians condemn Christ’s attitude as unloving.
It's always wise to first determine whether the recipient of your lecture is of the same faith as you. Because if they aren't, the point is lost.
The simple issue is, that I most certainly would not kick my kids out of the house or disown them because they "sin". See, I'm not perfect. I aspire to conduct my life as G-d would have me do. But I am not pompous or arrogant enough to condemn sinners so vociferously while being a sinner myself. That would smack of hypocrisy and would not go unnoticed by my children.
They would know that I disapprove..they would know that I love them...they would know that they have a home, always...Much more importantly, the fundamental question is whether or not we believe that a person is "born" homosexual or whether it is a developmental trait.
