Here's why we shouldn't support Israel's attack on Iran, argued from a Biblical perspective.

GENESIS 12:2-3 (NLT)

I will bless you and make you famous and you will be a blessing to others.
I will bless those who bless you and curse those who treat you with contempt.
All the families on earth will be blessed through you.

Keep in mind that the "you" being referred to here in Genesis is the family and descendents of Abraham.

Everybody likes shortcuts. Everyone, to some extent, is lazy. Genesis 12:2-3 allows Christians to form their position on Israel by memorizing that second sentence above, or some similar translation of it. Their understanding requires no real thought, just memorizing God's promise to Abraham. Yes, Christians are going to press the Easy button at times too. For this same reason, Christians default to supporting the state of Israel because that's the faster way to gain acceptance within the Christian community. "Supporting" Israel has become the ultimate virtue signal for Christians.

I don't argue with the premise that God will bless those who defend Israel. I believe God's word, just like the defenders of Israel do. The definition of "Israel" is what divides the Christian community. That is the key argument one must address when talking to Christians.

WHO/WHAT is ISRAEL?

Maybe we should start by asking who Israel is not? Go back to the first sentence quoted above from Genesis. Do we really think that "you will be a blessing to others" refers to the country of Israel or even Jews in general?  What blessings from God have they brought us? Go to the third sentence now. Do families around the world really feel like they've been blessed by their association with the country of Israel or the Jews?

Second, God loves both his children (defined as Christ followers) as well as those who do not believe in Jesus. Jews, unless Messianic, are non-believers. In John 8:42-44, Jesus calls ALL non-believers "the children of the devil". I'm sorry; but, according to the Bible: No, we are not all the children of God. The majority of Israeli citizens are thus "children of the devil". So, we should ask ourselves "Does God really want us to support or bless children of the devil"?
