Luke 17:22-37  The day is coming, Jesus teaches His disciples, when He will come again, " in His day."  But, before that He will be rejected and suffer.

The day of His coming will be like the days of Noah or the days of Lot.  In both these illustrations, life was going on normally for most people:

People were eating and drinking.
People were getting married.
People were doing business.
People were building new homes.
People were planting new crops.

But, Noah and his family were entering an ark.
And, Lot and his family were leaving town.

These two were willing to lose their lives - their homes, businesses, fields, friends... everything part of normal life, to preserve their real life.  Lot's wife left with him, but turned back, not willing to lose everything that she thought was more important.. and she ended up losing everything, including her own life.

Jesus tells us that "It will be just the same on the day that the Son of Man is revealed." 
Some will be sleeping.
Some will be working.

Some will be taken and some will be left.
Some will lose their lives because they are unwilling to give it all to Jesus.
Some will lay down their lives to follow Him and gain eternity.

Today is a day like any other.. for most of us.  We will eat and drink.  We will work. We will build or plant..we may even marry ( or celebrate our marriages).  But, what we do not know is whether or not Jesus will return today.  We must be ready for that day, like Noah.. prepared to be taken into the Ark of His protection.  We must be like Lot, willing to leave it all behind, in obedience and sacrifice.

To be ready.. for the day of Christ's return, or the day of our own death... we need to be completely committed to our Savior.. to the point that nothing else is worth turning back for.. at least no material things.  Both Noah and Lot took along the only things that really mattered.. their families.

Father in heaven,  You are holy and mighty.. and we glorify Your Name. All things are in Your Hands.  We are in Your Hands. O Lord, may we be fully committed to losing everything in order to gain eternity with You.  Hold us close and lead us moment by moment.  May our families know You and trust You also.. that we might all be together with You forever.  We pray this in Jesus' Name. Amen.
