It's always through "other christians" why do you not read for yourself in the bible? which of God's 10 commandments by breaking have you been set free from this "cruel Father" you talk about. Jesus has in no wise aolished the commandments, if you say that breaking them has "set you free" I must doubt that you are truly a child of God.
If you are filled with the Holy Spirit you will not wilfully break any of the 10 commandments.
Jesus warned plenty about the danger of hell, eternal punishment, it is true He scarcely ever directly threatened anybody, His warnings mostly are given generally but they are stark for all that.
The imputation of righteousness that God gives is not imaginary, it is more than a belief in the mind. Jesus was righteous, He did not sin. John says that we should walk as He walked, as He was in the world so should we be. We will overcome sin by allowing Christ to truly live in us.
God always uses people, whether prophets of the Old Testament or Apostles in the new or Christians. And they always, or should always, refer BACK to God's Word.
This is getting outside the main subject however it is true that Jesus did not abolish the law He FULFILLED it.
I was made free from the IDEA that my relationship with God is based on His Commandments. It is not. It is based on our Faith in the work of Jesus Christ and His sacrifice. We have PEACE with God THROUGH Jesus Christ. Commandment keeping doesn't make any of us RIGHT with God, we are MADE right with God THROUGH Jesus. That's the point.
We will fail if we are constantly thinking about keeping God's law or focusing on our sins (sin conscience) instead of focusing on God and Jesus. Does that mean we should break the law? Of course not but to keep God's law comes through our relationship with God.
In other words is your relationship with your Mother, Father, Brother, Sister, Son, Daughter, Friend etc. based on "laws" or Love? Love comes first then from that love we automatically keep God's laws. I had it backwards. Commandment keeping comes first then from keeping the law we automatically love God. That's wrong!
Who has a relationship with anybody based on "laws"? You can be my friend and I'll love you as a friend if you first abide by my list of do's and dont's on how to be my friend FIRST, THEN we can be friends. Isn't it normally you become friends first THEN based on that friendship, that relationship, you learn of each other's likes and dislikes and out of respect and love for your friend you approach them in a way that expresses that love? It is THEN you DO things as to not offend your friend, NOW that you know certain things about them. So I don't focus on "keeping" God's laws or on "my" sins. I focus on my relationship with God and Jesus who have made me acceptable, righteous and clean through Jesus. I have an open honest relationship with God the Father and tell Him everything. My fears, my weaknesses, my issues etc. I don't hide them from Him (as if I could anyways) but as my loving Father, like in any honest relationship, I have the confidense in His love for me to help me through anything. I don't feel condemned or even judged, I feel loved. Giving Him thanks always and praise for His great Love. THAT, is why I will not "willfully" break His commandments, not because of "fear" of breaking them but rather because of my "love" for Him.
It's much the same way in any relationship where you love another person. Nobody loves you because you're perfect or keep most of your friends "commandments". But as the relationship grows so does the maturity of that relationship.
To have Christ truly live in us, is to have a RELATIONSHIP with Him through the love given to us that is in us by His Holy Spirit. Which is a spirit of Power and a Sound Mind and Love. 2 Timothy 1:7 For God has NOT given us a spirit of FEAR, but of Power and of LOVE and of a Sound Mind.
