Love is the fulfillment of the law, Romans 13:8-10.  Sin is breaking the law, 1  John 3:4.  Love is what righteousness is and has many facets as 1  Corinthians 13 says.  God is love.  We cannot have righteousness  without having God.  We cannot have love without having God.  In fact,  righteousness is a free gift from God, Romans 5:17.  Righteousness is by grace through faith.  The children of Israel made  the mistake of trying to establish their own righteousness and so they  missed out on this free gift of God's righteousness, which God was  willing to give them at no cost, Romans  10:3.  Trying to put a little love in our hearts or to live by a set  of rules is futile.

If  we try to live by  laws and rules, we will either live in  self-condemnation or we will  live in self-righteousness.  If we  recognize the fullness of God's law,  and we try to obey it by our own  power or our own righteousness, then we  will condemn ourselves because  we will fall short.  Far more often,  we see people who modify God's law  into a set of rules that they can fulfill.  They  lower the bar until  they can fulfill their rules.  That always brings  self-righteousness  and pride.  God's law is clear.  Human beings cannot  fulfill it without  the process described in the Bible.   This is the righteousness, the  love,  that is a free gift.  This is the righteousness that is by grace  and through faith.  God does His works through us, and it is by the free  gift, grace, and that grace is only available through faith.  What  actually happens is that God loves through us.

We  need to ask God to help us to let Him love through us.  For the person that I'm having trouble  loving  at home, at work, at church, Lord,  help me to let You love this person through me.  We can do the works of  God if we will believe in Him to the point that we let Him work through  us.  When we try to generate our own love, it is like trying to  generate our own good works.  In fact it is exactly the same thing.  

The  reason that we must let God love through us has to do with the way  righteousness and love operate, faith or hypnotize yourself into believing.  Such nonsense has nothing to do with real faith.  This type of mind exercise is a deception from Satan.  God gives faith for those things that He desires.">Romans 10:17.  God  speaks to us.  We respond.  Faith is born in us by the power of God.   Faith opens the door to grace, Romans 5:2.  Grace flows in  and does God's works through us, Romans 6:13.  Whatever is not of faith is  sin, Romans 14:23.  In other words, anything that we do  that God did not lead us into and anything in which God did not do the  work through us is sin.  That narrow way is very narrow indeed, Matthew  7:13-14.   
So it is plain that we  are totally dependent on God to have love or to do any good work.
