He came to his own, and his own people did not receive him. ~~John 1:11 (ESV)
John 1:11 is, in my opinion, the most heart-wrenching verse in the Bible! But, like Israel, many Gentiles (including those who honestly believe themselves to be Christians) also close their hearts to Him, preferring to make Him a mere addendum to spiritual systems of their own design.
Thankfully, the real Jesus continues to offer Himself to those who truly want Him. As Israel prayed for His first coming, so we can individually pray that He'll come as the Ruler of our lives. He will free us, not only from sin's eternal consequences, but from its power to keep us from Him. And He will come again to take those who truly belong to Him to live in His Kingdom.
