After Jesus’ transfiguration, His disciples queried Him about something they had heard some scribes say: “‘Why then do the scribes say that Elijah must (return) first (before the Messiah)?’ And He answered them, ‘Elijah is coming and will restore all things; but I say to you, that Elijah already came, and they did not recognize Him, but they did to him (John the Baptist) whatever they wished. So also the Son of Man is going to suffer at their hands.'” Matthew 17:10-12 (NASB)
A few years ago, I heard a song titled Days of Elijah which looks forward to Jesus’ return.
These are the days of Elijah, declaring the Word of the Lord, And these are the days of Your servant, Moses, righteousness being restored.
And though these are days of great trials, of famine and darkness and sword, Still we are the voice in the desert, crying, “Prepare ye the way of the Lord.”
These are the days of Ezekiel, the dry bones becoming as flesh. And these are the days of Your servant, David, rebuilding the temple of praise.
And these are the days of the harvest, the fields are as white in Your world. And we are the laborers in Your vineyard, declaring the Word of the Lord.
Behold, He comes, riding on the clouds, shining like the sun, at the trumpet call. Lift your voice, it is the year of Jubilee, and out of Zion’s hill salvation comes.
A few days before His crucifixion, Jesus was already trying to comfort and encourage His disciples and give them hope for future events they would never see in their lifetimes here on earth:
“There will be signs in the sun and moon and stars, and upon the earth dismay among nations, in perplexity at the roaring of the sea and the waves, men fainting from fear and the expectation of the things which are coming upon the world, and the heavens will be shaken.”
“And then they will see the Son of Man coming in a cloud with power and great glory. But when these things begin to take place, straighten up and lift up your heads, because your redemption is drawing near.” Luke 21:25-28 (NASB)
