Of course the teaching of the Christian faith should include how we live in holiness and obedience, showing by our lives the faith we have. We love Him, Scripture says, because He first loved us. That's what the book of James addresses. It is what Paul taught for example in his epistles to the Corinthians:
What people should be careful of, though, is going to the other extreme where our works stop being an evidence of a changed heart and a new birth through faith, and go into making our works and deeds necessary to meriting eternal life. Paul dealt with that heresy repeatedly. We see him addressing it throughout his writings. He had to deal constantly with those called the Judaizers, who insisted Gentiles must be converted to Judaism and be subject to the Law of Moses in order to be saved. We read again and again where Paul admonishes believers to not be taken in by that error. For example, he said:
Salvation is the gift of God that we receive by faith. HE sees our hearts and we cannot fool Him by words we may say. Genuine faith WILL show in the life of the Holy Spirit indwelt child of God. Will we sometimes stray, mess up, commit sin? Yes, we are STILL in the flesh. But there is a difference now - there is a repentance, a sorrow when we sin against God, we feel shame over the wrongs in our life and we strive to live for God's glory. That's how we know the Spirit of God is working in us. I love what the following has to say about born again children of God:
Boatbums...one thing I’ve learned over the years is not to engage with those who take a platform so as to sermonize or preach. I am sure you are a wonderful person and live a righteous life. I hope you are kind and generous to your neighbor. With that I will say...may you be blessed. Thank you for sharing your thoughts.
