Absolutely, God is big enough. However, He did not leave us without a way to escape temptation. That is why the idea that one can be a homosexual only in the mind is lying to themselves. The Bible says that the heart is deceitfully wicked and who can know it? See Jeremiah 17:9.
OK. A passing thought and I escape temptation. Works for me.
"However, He did not leave us without a way to escape temptation."
Sorry, but no normal person can think homosexuality is "temptation", unless the person himself has latent homosexuality.
Temptation to adultery is real. Temptation to gluttony is real. But temptation to homosexuality for a normal person? Never!
