If you accept the invitation, does that mean you are saved?
I would say no.
I have invited many people to church.
They have come to church.
Some have left and some have stayed.
They sing the songs, listen to the service, get something out of it.
They resolve to be a better person, do the right thing.
A few I have asked when talking to them "Do you believe that Jesus is the son of God who died and rose again for the forgiveness of your sins?
They said "Yes Jesus died on the cross but did not rise from the dead"
I even had one person ask me to baptise him, I was not convinced he was a genuine beliver. So I asked him he question above, I pressed in and said to him "Are you willing to confess this? He said no.
So I said "Sorry I cannot baptise you"
A couple of days later he told me that he is not coming to church anymore, the only reason he wanted to be baptised was because he felt it was the right thing to do and wanted to be part of a community.
So I said to him you can still be part of our community, even if you do not believe still come along. He said "No I can't because Jesus did not rise from the dead and I never will
Yet I have 2 instances of the reverse.
They made it very apparent that Jesus was just a good man who gave us good teaching, how to walk and I do the same then maybe I'll get into heaven.
I have had the privilege of baptising both, they made that wonderful confession.
In fact one of them was so ardently against Jesus rising again yet wanted a connection to a God. Actually in fact he had an angst against God. Twice he tried to commit suicide and on both times he had to resuscitated, the second time 3 times and when he woke up he says to "F###, why have you not let me die you b#####d
It was such a privilege (after many months of walking with him) he called me and said "I need to talk to you"
We meet we talk he asks "Why can't I connect with God, why the disconnection"
I said to "Jesus is your connection"
He asks "What do I pray what do I say, I don't know how to pray"
I said to him "Just be honest, talk to him and tell him everything, he knows it anyway"
Long story short, he falls on his knees, and boy did pray.
He was totally honest, warts and all. He cried, shouted out, laid everything on the table.
The floor was wet with his tears, mingled with the snot from his nose.
Then he cried out "JESUS YOU ARE WHO YOU SAY YOU ARE I NEED YOU SO SO MUCH, I BELIEVE YOU DIED FOR ME AND MY SINS AND ROSE AGAIN, THANKS FOR NOT LETTING ME DIE WHEN I TRIED TO KILL MYSELF, THERE MUST HAVE BEEN A REASON AND THIS IT"
then he got up and boy was I shocked. A totally different person, a face full of burden but now released.
To be honest after that I went for a walk.
I just couldn't get my head around it.
A guy I walked with, ridiculed what I was telling him and me, then in the space of 2 hours it's all changed.
I was gobsmacked, yet humbled.
Being in the church and part of the Church does not make you believer placed faith in Jesus is accepting the invitation.
Jesus Christ who died and rose again, believe it and walk in it.
Just like the guy above is doing.
He is bearing so much fruit
