Don't feel bad. They feel good that just having right doctrine and knocking door to door earns them salvation...
Persecution just adds to their sense of righteousness.
Yes, but if only we born again believers had half the moxie of the J. W.'s...!
HOW TO WIN A JEHOVAH WITNESS (OR JEWISH PERSON) TO CHRIST WITH A KJV
(an NIV won't work)
------------ 1------------
Point him to Rev. 1:11 and read: "I am Alpha and Omega, the first and the last"
------------ 2 ------------
Ask him, "Who is the 'first and the last'? Who is speaking?"
------------ 3 ------------
Every J. W. (or Jewish person even slightly versed in scripture) will say, "Jehovah," based on Old Testament verses such as Isaiah 44:6 or 48:12 which say, "I am the first, and I am the last..."; "I am he..."
------------ 4 ------------
Then point him to Rev. 1:18, "I am he that liveth, and was dead; and behold, I am alive for evermore"
------------ 5 ------------
Ask him, "When was Jehovah dead?"
------------ 6 ------------
They then realize that Jesus Christ was "God manifest in the flesh" (I Tim. 3:16)
------------ 7 ------------
This technique has been used to lead more J. W.'s to Christ than any other. It works every time I've done it.
