Some people think that, because believers are saved by God’s grace in Christ, they can sin whenever they feel like it because God will forgive them anyway. A fancy word for this is antinomianism. This kind of cheap grace does not take into account the Holy Spirit’s work of sanctification in the lives of all Christians (John 16:7–15). All believers bear the fruit of the Spirit because they are branches attached to the vine of Christ (John 15:4–5; Gal. 5:22–23; Col. 1:10).

Costly grace is the Incarnation of God. — Dietrich Bonhoeffer, The Cost of Discipleship

Cheap grace is worthless. It tries to rob you of your peace and rest in Christ. Christians always need to be on the lookout for cheap grace and stay far away from it. Here are two kinds of cheap grace that pretend to be the costly grace God gives us in Christ:

1. Grace without Christ

Some people think that God saves us by his grace in Christ, but we must be obedient to get and keep God’s grace fully. There have been various words used over the years to describe this kind of cheap grace, including legalism, prevenient grace, works-righteousness, and covenant faithfulness. You can always recognize this kind of cheap grace by this one test: If someone is telling you that there is something you need to do to add to Jesus’ completed work on your behalf—that Jesus’ finished work is not enough to save you—then you need to run away from this false teaching.

Many Christians are told that this kind of grace is true grace; the people who teach cheap grace may be ignorant, thinking that conditional grace is God’s grace—but it isn’t. There are many verses in the Bible that affirm the truth that salvation comes from outside of us through the work of Christ, not from anything we do (for some examples, see Rom. 5:1; 6–8; 15–17; Rom. 8:1–11; 2 Cor. 3:4–5; 5:17; Eph. 2:8–9; Titus 3:4–7). The works James is talking about in his letter are the fruits of the Holy Spirit’s work in the lives of believers (James 2:14–26). These works do nothing to save a person; rather, they are evidence of a person’s adoption into God’s family in Christ.

2. Grace without the Spirit

Some people think that, because believers are saved by God’s grace in Christ, they can sin whenever they feel like it because God will forgive them anyway. A fancy word for this is antinomianism.
