If someone claims to believe in Jesus, ask them if they ever get hungry or thirsty. If they answer yes, that means they don’t actually believe in Jesus. If they answer no, you still need a little more evidence before you can conclude that they’re a believer.

Ask the alleged Christian if they obey everything Jesus commanded. Do they always give people whatever they ask for?¹ Have they sold everything they owned and given the money away to the poor? Do they hate their families? Do they let criminals mistreat them as much as they want without resisting? Do they mutilate their bodies every time they do something wrong? Have they demonstrated their love for their friends by killing themselves? Anyone who claims to know Jesus but doesn’t do what he commands is a liar.

Next, ask them to show you some miracles like Jesus did. Jesus says everyone who believes in him can do all the same things he did, and more! So have them start off with some of the miracles that Jesus did, like mind reading, turning water into wine, turning a little food into a lot of food, walking on water, flying, disappearing, controlling the weather, curing every disease, and raising the dead.
