Yes, it is as simple as the Sinners Prayer, and if they have never been baptized, just sprinkle water on them in the name of the Father, Son, and Holy Spirit once that prayer is done....the sick cannot be taken to be immersed.
God is love ....we have opportunities to bring our family to God. Don’t let that opportunity pass. I had an Uncle who was made ready for death in this very way.
There is a ‘peace that passes all understanding’ once they have made that commitment and the fear leaves them, because then they aren’t going to hell.
Jesus was clear and simple....
It is that Simple,,,,,Yes !
Jesus said ;
This Day You shall be in Paradise,
to one on the cross beside Him.
Thanks
