As I recall the term "head over heels" refers to someone "head over heels in love." That is a good position to be in; it sure beats being "up to your neck in debt!" When that happens we have fallen in, and are sinking fast! When we fall in love we stay afloat because there is a bright future in our plans. When we fall in the bottomless pit of debt there seems to be no way of escape. The apostle Paul gave guidelines we are wise to follow
"Owe no one anything except to love one another, for he who loves another has fulfilled the law (Romans 13:8 NKJ)." Our desire should be falling "head over heels in love with the Savior!"
