Does this offend you? John 6:61
Jesus had just finished teaching a large group of followers that He was the bread of life. He wanted them to understand that everlasting life comes from accepting His upcoming sacrificial death. This troubled most of the multitude. A humiliated, suffering Messiah didn't fit their understanding of God, and they began to murmur. Eventually they walked away.
At some point in our walk, we will come up against words Jesus spoke that are a little jarring. Or maybe something God said in the Old Testament will cause us to stop and wonder. God wants to reveal Himself to us. As He does show more of Himself to us, we will begin to see He cannot, will not, be confined to the safe boundaries we like to put Him in.
Jesus goes on to tell this crowd, What then if you should see the Son of Man ascend where He was before? John 6:62
To paraphrase, "If you can't handle this, there's no way you're ready for the big stuff."
God is not going to change to accommodate our notions of who He is or who He should be. So what do you do when you hit one of these things that rocks your theology? First, make sure it is a correctly interpreted Biblical truth and not just someone else's opinion. Check cross-references. Scripture NEVER contradicts itself, although our interpretations can't sometimes be off. Ask mature people you trust.
Then once you're sure you have understood what God said, you have a choice to make. Accept that you need to change your ideas and acknowledge who He is, or walk away.
After the crowds trickled away, Jesus asked the 12 if they were leaving too. Peter, without hesitation, replied, "Where else can we go? YOU have the words of eternal life."
They were glad they stayed around. You will be too.
