Here's a little history of the song from Wikepedia:
Martin Rinkart was a Lutheran minister who came to Eilenburg, Saxony at the beginning of the Thirty Years' War. The walled city of Eilenburg became the refuge for political and military fugitives, but the result was overcrowding, and deadly pestilence and famine. Armies overran it three times. The Rinkart home was a refuge for the victims, even though he was often hard-pressed to provide for his own family. During the height of a severe plague in 1637, Rinkart was the only surviving pastor in Eilenburg, conducting as many as 50 funerals in a day. He performed more than 4000 funerals in that year, including that of his wife.
If I were to say, “Life is a matter of heaven or hell and who you’re taking with you,” what would be the first thing you think of? For an unbeliever, this question can cause serious anxiety and doubt about the future, while at the same time, if you are a believer in Christ, you probably feel comfort and peace because you know with certainty that you will be spending eternity in Heaven. But what about the second part of hat statement? Who are you taking with you?
The things we strive for in this life mean nothing in the next--money, cars, property, prestige, popularity, position--you can't take it with you . . . but when it comes to relationships, that's a different story. You see, our relationships can last for eternity! Our friends, our family, our neighbors--they can come with us! Don't read too much into what I'm saying here--nobody knows exactly what our "relationships" will look like in heaven (read Matthew 22:23-33), but we do know
Have you ever taken a “leap of faith?”
It’s hard... really hard. Letting go of control is not something we mere mortals do easily, often because we forget we are mere mortals. We forget that we cannot see or control the future. Fear of the unknown can easily cripple us, causing us to make decisions based on insecurity. We put all our money into our savings, our 401Ks, our retirement plans, thinking that this is a wise use of our earthly wealth. I’m not saying that those things are NOT a wise use of your earthly wealth, but did you take a leap of faith first?
Fear of the unknown is overcome when we remember who controls the future . . .
You have been challenged by the Lord Almighty to take a leap of faith, and in turn, challenge HIM!
