Jesus died on the cross for our sins, and was resurrected in a perfect form, as an example of what we will be like in the resurrection.
That is true.
There was reason for my response to your post.
I have had the wonderful privilege of baptising people.
When baptising them, in the pool I always quote the passage from Romans.
When they ask me to be baptise them I ask them if they have done what the verses in Romans say.
Twice I had to say "Sorry I can't baptise you" the reason being is because they did not believe that Jesus rose from the dead.
That being the case I could not baptise them.
I walked with a guy for about a year (part of my ministry in church, discipleship)
He believed in Jesus as a person who died on the cross, came to teach us the way to live and show us God. mental health issues, tried to kill himself, when he was resucitated 3 times and woke up his words were "Why the f### f### have I woken up God I want to f###### die"
Long story short, he called me and asked if we could meet up.
We did, I let him talk.
He focused on the disconnect he had with God. Could not understand it.
I said to him "The disconnect is Jesus, you do not believe he rose from the dead"
He said "How can I connect with God"
I said "You can't, he connects with you"
I quoted the Romans verses.
He said I don't know how to pray.
I said prayer is not fancy words or bravado it's talking to God warts and all.
Then he fell on his knees, poured his heart out to God.
And he was totally honest (so honest it would make a sailor blush)
He cried, snot pouring from his nose.
I saw a broken honest man on his knees.
Then he said "Jesus I thank you that you died for me, that you love me and that you rose again for me and they I'm reconciled to God"
I'm sat there thinking WOW what's going on here.
Then he got off his knees stood up and I saw I totally different person.
It was like a weight was lifted and I saw it in his face.
He said "Bill I feel released, my body is tingling, I feel warmth I am connected to God, then he said THANK YOU JESUS MY SAVIOUR, THANK YOU GOD FOR THE DOCTORS WHO RESUSCITATED ME BECAUSE YOU HAVE A PURPOSE FOR ME"
I have had the privilege of leading only a few people to Jesus.
But for the rest of that day I was gobsmacked, I'm thinking what on earth has gone here.
A man for a whole year who refused to believe Jesus rose from the dead and within an hour came to believe it.
I had the privilege of baptising him a month later.
And boy is God using him.
I believe he was saved before he was baptised.
