Another divine equation is the duality of Christ in us....and we in Christ.
We bear fruit only as both are accomplished. The Lord does the first as a free gift...a surprise really...a calling and a potential to know the Lord.
The other costs us everything to have.
It is like going to a store to try out a perfume sample. The sample is real and it is free! But the price of the bottle...if we wish to fully have the perfume....is ALL we have. Very very few people are willing to give all to have Christ. Many many people love the free stuff. They want the free sample....but NOT the expensive product.
So most Christians stay on one side of the equation while arguing that there is no other side. They will say that they already fully abide in Christ...they will say they are already fully crucified. But they remain sinners and now...liars because they have not understood the truth. And they will be very stubborn in the denial of the truth!
