Evangelical Christian support for Donald Trump seems bizarre to me.
Trump himself is a programmatic anti-Christian; a serial adulterer, sex abuser, slanderer, liar, and hedonist. When asked in an interview, he couldn’t even come up with his two favorite Bible verses. When asked again, it said, “an eye for an eye.” When asked what he had asked God for forgiveness, he couldn’t come up with anything.
But the rationale Evangelicals have for their support of Trump is that he is a “flawed vessel” of God.
The Guardian newspaper said:
A sustained effort by influential Christian voices to justify Trump’s personal misdeeds and political cruelty has led to the frequent portrayal of Trump as a flawed vessel for God’s will. In particular, Trump has been compared to King Cyrus, who, according to the Bible, liberated the Jews from Babylonian captivity, despite himself being a Persian ruler.

Cyrus is the wrong model. I think the Kingdom of God would be better served if Evangelicals listened to Jesus rather than the Trump apologists:
Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus you will recognize them by their fruits.
Matthew 7:15–20 ESV
