Gerryh: Religion = Performing works to gain salvation. Such as adherence to particular ceremonies, rules, laws, good works. Faith in Christ = freely gaining salvation by the grace of God. It is given to those who trust in Christ.
Galatians 5
It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery.
2 Mark my words! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all. 3 Again I declare to every man who lets himself be circumcised that he is obligated to obey the whole law. 4 You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace. 5 For through the Spirit we eagerly await by faith the righteousness for which we hope. 6 For in Christ Jesus neither circumcision nor uncircumcision has any value. The only thing that counts is faith expressing itself through love
Religions seek salvation through works. False teachers taught amongst other things that the act of circumcision was necessary for salvation. The apostle Paul is saying it does not matter if a person is circumsised (adheres to laws and rituals). It is an indifferent act in regards to salvation. The person who relies on religious activity (lighting candles, praying the same prayer 100 times a day, or any devised work) is in bondage. A person who believes a particular act/ceremony/ritual is necessary for salvation must then follow the ENTIRE LAW. That person then obligates himself to fufill everything that is required in the law. No one can seek righteousness before God through their own efforts. They have to go through the narrow door. Only Jesus saves. We can in no way, by any effort save ourselves.
13 “Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. 14 But small is the gate and narrow the road that leads to life, and only a few find it.
