A comment by a friend the other day caused me to stop and think.
What do I mean by 'Law and Grace', how does they work out in my life?
The law shows me my lawlessness.
There is no law which deals with / absolves me from the guilt of my sin.
In the book of Leviticus we read that sin can only be dealt with by the shedding of blood. A fact highlighted later, following the death and resurrection of Jesus, by the writer to the Hebrews (Hebrews 9:22).
The writer to the Hebrews goes on further to explain that the blood of Jesus dealt with sin once and for all, in the book of Romans Paul explains that we appropriate the benefits of that by faith.
John the Baptist declared Jesus to be "The lamb of God, who takes away the sin of the world" (John 1:29). The Apostle John wrote "... to those who believed ... he gave the right to become children of God" (John 1:12). In John 14:1-15:17 Jesus speaks of the Spirit living in us, which is a fulfillment of Ezekiel 36:26-27, the promise of an inward change.
I receive grace not because of who I am or what I do but because of who God is (Jahweh - I AM) and because Jesus lives in me! Jahweh gives me grace because of Jesus. He is the new man in me teaching and demonstrating God's relationship together in me.
Paul taught about walking in the Spirit and the fruit which will become evident in our lives (Galations 5:13-26). Jesus said similar about the fruit seen in our lives (Matthew 7:17-20), that which comes out from within us. What seeds am I sowing in my life - what harvest am I (or will I) reap as a result?
In Exodus we find that the law came through Moses. Throughout scripture we find Moses represents the law. Moses did not take the people into the promised land - that task fell to Joshua. Common Hebrew equivalents of Joshua are Yehoshua and Yeshua. From this name, through the Greek, we get the name Jesus ("The lamb of God, who takes away the sin of the world")! So in scripture we find that Joshua represents Jesus.
