"You will know them by their fruits" (
Matthew 7:16).
It's obvious that Donald Trump only invokes Christ's teachings because he knows it tickles the ears of his devout Christian voting base. It's obvious (by his vindictiveness and maliciousness) that he doesn't genuinely believe anything he spouts about Christ's teachings or else it would be demonstrated by the fruit he bears in his life. However, he doesn't bear good fruit in his personal life. He bears the fruit of hatred, discord, jealousy,
fits of rage, selfish ambition, dissensions, and factions. It is as clear as day that he bears the works of the flesh (
Galatians 5:19-21) in his life. He certainly doesn't bear the Fruit of the Spirit (love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness, self-control).
Jesus said, "Out of the abundance of the heart the mouth speaks (
Matthew 12:34). It is clear to see what is in Trump's heart because of all the maliciousness he spews out of his mouth. He viciously slanders anyone who opposes him, he disparages anyone he hates, he cruelly mocks people, he takes God's name in vain, he uses profanity to express his anger and displeasure, he bears false witness, and he's notoriously known for his lying tongue and deceitfulness. He perpetually lies and cheats.
He is a very cunning and deceitful man, so he knows what melody to play to get people to follow him and he plays other people like a fiddle. He uses and manipulates people to his personal advantage. If he genuinely believed in Jesus Christ and believed the teachings of Christ, then it would demonstrated in his words and in his behavior. However, it isn't. He only speaks Christianese and puts on an act like that because he knows that it will entice his devout Christian supporters and keep them all appeased.
"You brood of vipers, how can you who are evil say anything good? For the mouth speaks what the heart is full of. A good man brings good things out of the good stored up in him, and an evil man brings evil things out of the evil stored up in him." (Matthew 12:34-35)
"No good tree bears bad fruit, nor does a bad tree bear good fruit. Each tree is recognized by its own fruit. People do not pick figs from thornbushes, or grapes from briers. A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of." (Luke 6:43-45)
