How would you answer ?
Humbly, I am not sure I am the one to determine what the biggest misconception may be, but let me offer this thought. I wonder if a key misconception that unbelievers have about Jesus is that he is dead!
It is much easier to disregard someone if they are not around. If unbelievers only see Jesus as some man back in history who died on a cross, and not as the one who rose again to life to take his place in glory, then it makes sense that they will disregard Jesus. If you think someone is dead, then their impact is only going to be at best by influence, certainly not by obedience or devotion.
1 Peter praises God because in mercy he has given Christians new birth into a living hope through the resurrection of Jesus Christ from the dead (1 Peter 1:3). It is a new birth with benefits! An inheritance that can never perish, spoil or fade – kept in heaven for those in faith, that is, those who love and believe in Jesus (1 Peter 1:4, 8).
The key reason why Christians can have hope in heaven and a hope for our future is because Jesus is alive. It is in his resurrection that we also live.
But let me ask another slightly different question.
‘What do you think is the biggest misconception that Christians have about Jesus?’
I am sure it is not that he is dead! A key distinction between the unbeliever and believer is that the believer holds to the living hope of Jesus. But given this is a key distinction, why is that often not more obvious?
I wonder if a key misconception that Christians have about Jesus, is that to be Christian we do not need to look that different to the rest of the world!
1 Peter addresses that issue as well.
As obedient children, do not conform to the evil desires you had when you lived in ignorance. But just as he who called you is holy, so be holy in all you do. (1 Peter 1:14-15)
Be Holy. Prepare your minds for action, be self-controlled – live counter-culturally to the world around us. Yes be a good person, the world wants you to be that – but don’t stop there! Be holy, because Christ without blemish or defect chose you – and so we can, in fact we must, live as one who obeys the truth.
The living one we serve is not the dead man our world thinks they know!
Let’s live obediently rather than die in compromise.
