The true ‘cure' is a lifetime of experience of God's grace and forgiveness, and to have the power of the Holy Spirit to live a godly life, whatever our circumstances. We may experience a complete change in our sexual orientation, or we may experience very little change - the Bible never teaches us to expect this kind of healing. However the Bible does teach us that the Lord is committed to our ongoing sanctification (2 Corinthians 3:18), and that includes our sexuality and all that is connected with it. This should give us a balance between a realistic and godly hope for change, and a realistic and godly acceptance that complete transformation is never guaranteed this side of heaven. "Godliness with contentment is great gain" (1 Timothy 6: 6).
