Sin is not an option for the believer. How can you continue in sin when that sin was paid for in the torn flesh of Jesus? How can you look longingly upon Satan’s offerings when the cross of Christ is in front of your eyes? Christ’s love constrains our hearts to seek holiness. The fact that sin has no lasting benefits remains true, but it is not simply because sin doesn't pay that you are to turn your back on the tempter. The fact that sin will not get you what you really want in life is not nearly a powerful enough defense to guard you against the attractiveness of Satan’s lies and the fickleness of your heart. Only a deep grasp of the gospel has the power to bring about deep change in your heart. It is knowing the terrible price that has already been paid for your sin that enables you to say no to sin.
