“Here am I. Send me!” are probably the five most scariest words you’ll ever utter to the Lord. It may come immediately after hearing that still small voice…your spirit bearing witness to the authenticity that it’s truly a Word from God. There’s no uncertainty or confusion on your part…for you know, that you know, that you know it’s from Him. But it also may come only after days, weeks, months, or years of a relentless voice that seems to grow louder and more persistent with each passing day, despite how much you try to ignore , or make excuses for why you can’t do what God is asking. When God asked, “Whom shall I send?” it was merely a rhetorical question…for He already knew the answer. But what God was really asking for was Isaiah’s obedience.
