The title of this post is somewhat naughty, almost like the question, “Does God believe in atheists?” By “Calvinist” I mean someone who follows the teachings of John Calvin. The name John Calvin is a swear word to many, but I hope to show you that Calvin’s theology should be our theology because it was a biblical theology, indeed the theology of Jesus Christ himself.
Could a Christian lose their salvation? Could a Christian in a time of weakness sin greatly and forsake Christ? Could a Christian in a time of deep depression deny their Lord? Could a Christian in a time of difficulty and hardship backslide spiritually and forsake Christ? Could I somehow or another loose my salvation? The Bible says: no. The thought that you could possibly lose your eternal salvation can be the cause of great anxiety. It is good to remind ourselves that our salvation is secure, not because of us, but because of God.
Can a Christian loose their salvation? The Bible says no.
The last point of Calvinism is: The perseverance of the saints. Perhaps a better summary would be: God’s preservation of the saints or God’s persevering with the saints. (BTW “Saints” is the word the New Testament uses for regular Christians.)
The Westminster Confession of Faith has a great definition of this doctrine. It says, “They whom God has accepted in his Beloved, effectually called and sanctified by his Spirit, can neither totally nor finally fall away from the state of grace; but shall certainly persevere therein to the end, and be eternally saved.”
