..if one cannot follow the ten commandments, they do not have love of God or love of neighbour..
Its because of Gods love for mankind that He gave us grace, it is because of Jesus's love for mankind that He willingly went to the cross for us, so that we would not be condemned by our sin because God knew that no man would EVER be able to keep the law, not even you. and so it was that Jesus
Act 2:23 Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain
Was slain for us
That is why in revelation it says
Rev_5:3 And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon.
Rev_5:4 And I wept much, because no man was found worthy to open and to read the book, neither to look thereon.
But you somehow seem to think that the law will perfect you, It is by grace we are saved, through faith not by our works because it makes people boast.
You say it cant save you yet it is exactly what you are trying to do, prove yourself worthy by your works.
