Lily, Doug's so-called corrections of what I said in #172 is actually the false teachings. He is an example of one who misinterprets several scriptures to make them mean that we can be saved by being baptized in water. Paul was adamant that no one can be saved by works. Look at Romans 11:6. Being baptized in water is a work - yes, it is commanded by Jesus, and we all should be baptized AFTER we have been born again, but that does not change the fact that it is a work, and Doug believes we are saved ONLY when we are baptized. This is false teaching. We are saved by grace through faith, not by being baptized in water. Ephesians 2:8-9.
Water baptism, ideally, should be the first work that we receive or do AFTER we're saved and AFTER our sins are forgiven. Baptism is a "picture" of the salvation that we received from Jesus. It is NOT the salvation itself.
Arguing about theology is not fun, but when people twist the truth, it is necessary to defend the truth. Jesus said, "If you are truly My disciples, you will continue in My word, and you shall know the truth, and the truth will make you free." When people stray from the truth, they cease to truly be free - rather they are enslaved by the lies of the devil.
Lily, I highly recommend listening to Steve Gregg on thenarrowpath.com for a clear understanding of scripture. It's free to listen to and will greatly enhance your understanding of the truth of scripture. Doug will most likely speak negatively about Steve, but don't let him dissuade you. Steve has been teaching the Bible for over 55 years, from Genesis through Revelation. He also has a daily question and answer radio program, live each weekday for one hour. You are free to call in with any questions, but call early, because the lines fill up fast. He has also written 4-5 books. If there is a difference of opinion about a certain passage, and there almost always is, he will give you the different opinions, and then he will give you his opinion and scripture to back it up.
May God bless you as you seek the truth. The apostle John said in 3 John 3-4 "I was very glad when brethren came and testified to your truth, that is, how you are walking in truth. I have no greater joy than this, to hear of my children walking in the truth."
