I have a fearful Christian friend (very conservative on social issues, and reads Bible in literal terms) who is a pastor's daughter. She is the most prayerful Christian I know (deep faith, prays every meal, etc.), however she is fearful she will not go to heaven if she does not answer God's call to the fullest. She is still figuring out God's call for her life. She told me a story of a pastor who did not speak the full truth/stay true to the call and once he retired, he had a dream which shows that God is not happy with him. The man trembled at this dream and sought forgiveness, and began to warn others. I think my friend is being too hard on herself, but I'm also scared by this story. The thing is, she is fearful and wants to be a missionary but she is getting her PhD in a completely unrelated field. So, I'm not sure exactly how fearful she is. I am also bit confused why some Christians believe simple faith is enough, but for others they see themselves as failures if they do not fulfill God's call which is epic/Moses level where it seems faith alone is not enough. Not really asking a question here, but please feel free to post your thoughts.
I would suggest (but I do not know) that your friend is right to be fearful, because she is relying on her works to save her (see text in red). These will not save her, and indeed, if she relies on them, will damn her. We are saved through Christ alone.
Matthew 7:21-23 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven;
but he that doeth the will of my Father which is in heaven.
Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
John 6:28-29 Then said they unto him, What shall we do, that we might work the works of God?
29 Jesus answered and said unto them,
This is the work of God, that ye believe on him whom he hath sent.
Let me repeat - we are saved through Christ's work alone. It is well to work our hardest in thankfulness for Christ's saving work on the cross for us, but we must always be assured this plays no part in our salvation, because we absolutely cannot love the Lord our God with all our heart, with all our mind, with all our strength, and with all our soul, neither can we even love our neighbours as ourselves.
