That’s what I used to think (John 10:9): “That if you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved...”.
Of course we don’t know 0’s heart, but he supposedly confesses Jesus as his Lord.
HOWEVER, he has spoken and enacted legislation very contrary to Christian doctrine. So now I do question his faith.
A bad tree cannot produce good fruit.
By his fruits you shall know him.
Mathew 7:15-20
“Watch out for false prophets. They come to you pretending to be sheep. But on the inside they are hungry wolves. 16 You can tell what they really are by what they do.
“Do people pick grapes from bushes? Do they pick figs from thorns? 17 In the same way, every good tree bears good fruit. But a bad tree bears bad fruit. 18 A good tree can’t bear bad fruit. And a bad tree can’t bear good fruit. 19 Every tree that does not bear good fruit is cut down. It is thrown into the fire. 20 You can tell each tree by its fruit.
