Sin is a negative reaction to God’s love for us.
“Sin is a negative reaction to God’s love for us.”
Sin is a rejection of God’s love not a negative reaction to it. If it were a negative reaction to it then people would never agree to enjoy it in the first place. Instead, what we do is knowingly reject it rather than negatively react to it (as if it were new and unknown to us).
