I'm not sure if this qualifies or not, but here was one of my very first "WOW!" moments:
When I first got saved 27 years ago, I immediately had an insatiable desire for the Word of God. IOW, as in the case of the newborn babe whom Peter described, I earnestly desired the sincere milk of God's Word as if I couldn't live without it. Of course, the natural outflow of that was that I had an earnest desire to speak of Christ and His Word to others, but that wasn't going over too well...and especially not with the "Christians" from my church. I was constantly criticized, nay, condemned, for simply wanting to talk about Christ. It was as if that every time that I simply mentioned something that He said, without even any commentary of my own, somebody or somebodies got extremely angry with me. I remember lying on my living room floor at home one day, totally crushed and discouraged as if there was something wrong with me, when I heard the Lord say the following to me:
"Out of His mouth went a sharp two-edged sword." (Revelation 1:16)
I had to look it up to see where it was in the Bible and then God took me through several other passages along the very same lines. IOW, God showed me, early on in my Christian walk, that if I was going to speak the Word of God to people or if I was going to have the same sort of "two-edged sword" in my mouth as Jesus had in His, then I should expect the same types of responses that He got. Some people were "cut in their hearts" by this "two-edged sword" and it led them to repentance. Others were "cut in their hearts" by this "two-edged sword" and wanted to kill Him. Anyhow, my "WOW!" moment was in that God was showing me that I needed to be faithful in speaking His Word regardless of how others responded to the same and I've hopefully remained faithful to the same over the years.
