One day (within this year or last year), God was dealing with me about these two phrases: "double portion" and "double blessing." These two phrases stem from Deuteronomy 21:17, but more importantly Job 42:10 (with this post focusing on the latter).
I have found that many people rejoice (even to the point of being hysterical) the moment they hear these words (whether it be a song or from behind the pulpit), "your latter will be greater," "the double portion is over your life," or "God is getting ready to take you into the overflow." I'll be honest, I kinda cringe when I hear those phrases because in most cases it's taken out of context. Let me explain.
If you were to read the entire book of Job (but especially chapters 1-2), you'll find that Job was blessed, but Satan wanted to attack Job to determine if Job will curse God. Now, when God blessed Job in chapter 42, it was after Job acknowledged that God is sovereign and after Job went through this intense spiritual warfare.
Many people today (especially those who are great at lip service) make a serious mistake in thinking because they go through (as a result of their own sin) that God's going to bring the double portion. Now I'm not saying He won't, but we understand there's a process: the double portion should not be the first thing on our minds. If it is, then we are just materialistic (case closed). And many people in the church world are just that. The double portion should be the last thing on our minds. Now if He happens to bless us that way, praise God; and if He doesn't, we should still be praising God. Not because of what He does for us (which was actually an accusation Satan made to God against Job), but because of who He is, His sovereignty and because He called us out of darkness into His marvelous light.
