I don't doubt your experience with the JW's since in all circles in life there is always bad, even among Christians and followers of Christ. We must remember however, that just because there are always rotten apples in a bunch of apples it doesn't mean that all the apples are bad. Among Jesus closest companions he had Judas Iscariot, a thief and a betrayer, does such a wicked man also discredit his companions?
We cannot earn salvation. As I mentioned earlier worldly organisation offer many free prize draws, it costs absolutely nothing to enter these prize draws and when/if you receive the gift, no amount of work provided that gift for you, since to enter the prize draw was free. However, prize draws always have T&C, this doesn't negate the fact that the prize draw along with the gift is free does it now.
I showed you the scriptures, you made no mention of them, they clearly show that obedience to Gods T&C's are needed in order to receive the free gift, JUST like a modern day free prize draw.
Since you clearly deny scripture can you answer simple some simple questions.
According to Hebrews 5:9 is Jesus responsible for the handing out the free gift of eternal life only to people who obey him?
(Hebrews 5:9) "..And after he had been made perfect, he became responsible for everlasting salvation to all those obeying him.."
Regarding the commission to preach(Matt 28:19 and obedience coming into play) we have Romans 10:10 which reads "For with the heart one exercises faith for righteousness, but with the mouth one makes public declaration for salvation". Do we need to publicly declare Jesus for salvation according to Romans 10:10?
According to Matt 7:21 will those who DO NOT do the will of God enter in the Kingdom? “Not everyone saying to me, ‘Lord, Lord,’ will enter into the Kingdom of the heavens, but only the one doing the will of my Father who is in the heavens will. (Matthew 7:21)
Another scripture to study Lon.
(Hebrews 10:36) "...For you need endurance, so that after you have done the will of God, you may receive the fulfillment of the promise..."
