It all starts with the free time that you have. After that, you make some conscious effort to "make more time" for it. Until, finally, you use all your time for it.
When faced with a life-changing decision like following Jesus, pursuing your dream, or putting up a business, you start with the free time that you have. You start only with your “available” time.
But, as your dream grows or as you follow Jesus more, you make more time for it. You make yourself more available. Until, finally, you commit all your time and your whole life to it.
But the first question is always, "Are you available right now?"
When faced with a life-changing decision, say "yes" when you're available. Try to see if it works for you. If it does, then make yourself “more" available until you can commit all your time for it.
Besides, life-changing decisions are more often decisions for the better. Because if they're not, you can always stop. But, try them out first when you're available.
I'm so glad I was available that one fateful day in October of 2011—the day I started serving God. More importantly, I'm so glad I said yes. That day changed my life for the better.
Then I heard the voice of the Lord saying, “Whom shall I send? Who will go for us?” “Here I am,” I said; “send me!” — Isaiah 6:8
