Galatians 4:29 At that time the son born according to the flesh persecuted the son born by the power of the Spirit. It is the same now.
What is one of the major themes we see, right from the beginning of our human existence? Jealousy and persecution against God!
God may have put everything in place, but we have covered things over time and time again with our petty fighting and insults which have even lead to wars!
Do not put aside the things God has put in place just because you want things your own way – God has done this all for a reason and we need to stop and take notice!
