"Homesickness" is a longing in the heart for home!
The summer I was six, I went to camp for the first time. Before I went, I discovered Psalm 27:10 - "Though my mother and father forsake me, the Lord will receive me." I carried that verse in my heart to camp! It kept me from being homesick even one time. In my child's view, "forsake me" included leaving me at camp. My focus was that God would pick up the slack, so to speak. I was able to trust Him to do just that.
"Homesickness" is usually a sadness that might even verge on sickness with a longing for home. When my grandchildren visit and decide at bedtime they want Mommy or Daddy and the tears start, I tell them, "You can go home tomorrow morning. Let's go to sleep now, and I'll call Mom and Dad in the morning if you still want to go home." So far, they always change their mind by morning!
Today the sermon was Luke 17:20 - 37. Jesus answers some questions about the Kingdom of God. Jesus tells His main men (His disciples) that it is a good thing to "long" to see the Kingdom come. This world isn't our final home if we belong to God's forever family! It's okay to be homesick for heaven! I sat there thinking that longing for God's KIngdom to come - for Jesus to come back - longing to go to live forever in heaven is a good thing! In fact, it is what we should feel! We should live every day wanting to be in that better place and ready to go there but still willing to live and work to bring in God's Kingdom on earth as long as we live in this temporary home.
Being homesick for heaven is good! Jesus gives us that longing in our hearts! This world is NOT our real home - thankfully! We are just passing through on our way to our real home if we know and love Jesus!
