There’s nothing cheap about being a Christian. Our salvation cost God His only begotten Son. Our salvation costs Jesus His life. And it costs us something too!
It’s common to hear someone say something along the lines of “When Jesus went to the cross for you, he paid the price in full. There’s nothing left for you to do. No doubt, you and I can never earn our salvation. But that does NOT mean our salvation comes at no cost to us!
In Luke 14:27-33, Jesus taught, “And whosoever doth not bear his cross, and come after me, cannot be my disciple. For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it? Lest haply, after he hath laid the foundation, and is not able to finish it, all that behold it begin to mock him, Saying, This man began to build, and was not able to finish. Or what king, going to make war against another king, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand? Or else, while the other is yet a great way off, he sendeth an ambassage, and desireth conditions of peace. So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.”
