Rebuilding the Foundations
Long ago, I heard Hank Hanegraaf, while he was still a Protestant, say on the radio that 2 Peter 2:20 is a difficult verse that needed to be interpreted in light of the clear verse John 10:28.
Let's look at 2 Peter 2:20:
For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overcome, the last state has become worse for them than the first. (ESV)
I chose the English Standard Version because it happens to be the one I'm reading right now on the Bible program on my computer. There is no dispute over the translation of this verse. Hank Hanegraaf was not complaining that the verse was translated wrong. He thought the verse was difficult because of what it plainly says.
On another radio program, I heard Bob George say that 1 Corinthians 15:28 is a difficult verse. It tells us that God will put all things under the feet of his Son, and once everything is under his feet, then the Son will turn everything over to God and subject himself as well, so that God may be all in all.
Granted, what exactly is meant by God being "all in all" could be questioned, but the rest is quite clear.
