Can you lose your salvation once you have become a Christian? Always thought of this question and usually lean towards the "Yes, once saved always saved" answer. But after reading a few passages, it seems to be written very clearly:
What good is it, my brothers, if a man claims to have faith but has no deeds? Can such faith save him? Suppose a brother or sister is without clothes and daily food. If one of you says to him "Go, I wish you well; keep warm and well fed," but does nothing about his physical needs, what good is it? In the same way, faith by itself, if not accompanied by action, is dead.
But someone will say, "You have faith; I have deeds."
Show me your faith without deeds, and I will show you my faith by what I do. You believe that there is one God. Good! Even the demons believe that-and shudder.
You foolish man, do you want evidence that faith without deeds is useless? Was not our ancestor Abraham considered righteous for what he did when he offered his son Isaac on the altar? You see that faith and his actions were working together, and his faith was made complete by what he did.
James 2:14-22
This verse shows how important deeds goes together with faith. Faith without deeds is dead! ONE MORE PASSAGE! READ ON!
God is not unjust; he will not forget your work and the love you have shown him as you have helped his people and continue to help them. We want each of you to show this same diligence to the very end, in order to make your hope sure. We do not want you to become lazy, but to imitate those who through faith and patience inherit what has been promised
Hebrews 6:9-12
Show the diligence of a Christian, not just by going to church on Sundays but living a life pleasing to God and a life dependent on God until we die. So that we can be sure of our salvation that is promised to us.
It is an inconvenient truth to many Christians, and many are "Christians" to get their ticket to heaven, but have we ever thought maybe in the first place we weren't even Christians at all? Remember faith without deeds is dead?
