If Paul the apostle had not stood up for the revelation of grace that was given to him by Jesus Christ, Christianity would have become simply another branch of Judaism (Acts 13:38-39). Even today there are still some religious groups who would seek to place the Church under parts of the Law of Moses as a symbol of true spirituality or as a necessary requirement for salvation. The problem with that is that it is not possible to divide the law up that way. If you break one part of the law, you have broken it all (James 2:10).
There may not be attempts today to have you circumcised in order to be saved, but the enemy works in more subtle ways. For example, there is the teaching that if you don’t keep the Sabbath, you cannot be saved (Romans 14:5). Or, if you do not speak in tongues, you are not saved (1 Corinthians 12:30). Or, if you are not water baptized in the right name and by the right denomination, you cannot be saved. In other words, Jesus didn’t do enough on the cross. This is blasphemy (John 19:30; Hebrews 10:1-10)!
So, beware of those who seek to place you under bondage to some rules or system as a means of salvation (Colossians 2:16-17). Stand strong in the grace of Jesus Christ (Galatians 5:1), my dear family, for it is the gospel alone which is “the power of God unto salvation” (Romans 1:16,17), and which makes all things new (2 Corinthians 5:17).
