Ed Welch says there are 2 main ways we can define legalism:
- an attachment to specific rules, so that we make the Bible say more than it actually does say on issues like card-playing, dancing or drinking alcohol (it's always someone else who does this, of course, never me!)
- adding something to the death of Jesus, so that we are made right with God not only by faith in Jesus' death, but also on the basis of what we do
But it's not normally as blatant as this, is it? Most of us wouldn't say " I need to believe in Jesus and also do x and y to be accepted by God." We know it's only through faith in Jesus' death that God makes us right with him.
For us it will be more subtle.
Perhaps we have a "good day -bad day" mentality. We expect God to bless us on days when we've had our quiet time, but on days when we've skipped our quiet time and been grumpy with our children, we don't expect God to bless us. In other words, we're making God's blessing dependent on what we do rather than on Jesus' death.
Perhaps we wallow in guilt when we've done the wrong thing, and feel like we have to "fix things up" before we can approach God in prayer. Again, we're adding something to the death of Christ: it's not enough to believe in Jesus, I also have to make things right with God before he will be happy to hear my prayers.
Perhaps we're anxious or depressed because we've failed some invisible standard. At some level, we feel like we have to prove ourselves to God, others or ourselves before we can be content. We're putting our security in something else besides Jesus' death: in the opinion of others, or in our self-opinion, or in earning God's favour.
Or perhaps, as I talked about here, it's that we think rules, regulations and vows are the way to grow in Jesus. We become Christians through faith in Christ, but we grow as Christians through disciplines and programs. I'll talk more about the alternative to this view in my next post on Tim Chester's You Can Change. But again, it's a way of putting our hope for transformation in something besides the death of Christ.
If you're still not sure what I mean by legalism, please ask me to clarify in the comments! Legalism is a slippery concept, as Nicole observed here. But I think it's really important to understand legalism or we'll fall into the same error as the Galatians, who thought circumcision was necessary as well as faith in Jesus; or the Colossians, who thought that we grow through rules and self-denial rather than through the gospel.
To add to the cross of Christ is to say that the cross of Christ is not enough.
