"For that ye ought to say, if the Lord will, we shall live, and do this, or that" James 4:15.
Life is all about planning for the future. It starts when we are young. We dream about what we want to be when we "grow up." As a child we can hardly wait until we reach that magical age of 13 when we become a teenager. It is at this stage that we know just about everything there is to know and surprisingly we know more than the adults.
Then we start looking forward to the freedom of age 16. At this stage we get that coveted driver's license and if we are lucky we get a set of wheels so now we can drive on our own. The novelty of driving soon wears off and we start thinking about how great life will be when we graduate.
After that, things like landing our ideal job, getting married, having kids, buying that first home becomes our focus. It never stops. There's always something ahead that threatens to steal our focus--even if it's just looking forward to the weekend. Left unchecked, those things have the power to prevent us from doing anything meaningful today.
It's not bad to look forward to things, but life is short. It is not part of God's plan to waste any moment, day, week, or stage of your life. It is not His plan for you to focus on tomorrow, because, truthfully, tomorrow is a mystery. You don't know what tomorrow will bring.
Whether you're looking forward to something or dreading it, the lesson is the same: God never intends for the focus on tomorrow to be your focus today. We do not know what the future holds but we can know that God holds the future.
