Hello Ciliegia, and welcome to Worthy.
I have a feeling you don't want justice but the freedom and liberty that Christ Jesus promises to give to all that come unto Him. Speaking of God's Law in the Old Testament, Paul says that Christ Jesus law in the Spirit has free us the law of sin and death (law of the Old Testament).
For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
We see that we are all sinners (Romans 3:23) and because of sin we must all die (Romans 5:12). But because God the Father loved us so much He gave His Only Begotten Son to die for our sins (Romans 5:8-10); and by doing this if we accept what Jesus Christ the Son of God did for us, the wages of sin which is spiritual death, is pass from us, so that we might have eternal life:
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. Romans 6:23 This gift is given because of all man Jesus Christ was the only Man that death could not keep in the grave (I Corinthians 15:3-4), for Jesus is the Only Man without sin (II Corinthians 5:21). And all one has to do to receive this gift is the following:
9) That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shalt be saved.
10) For with the heart man believeth unto righteousness: and with the mouth confession is made unto salvation.
Basically just pray to God the Father stating I know that i am a sinner and I turn from my sins, and I believe and accept in my heart, that Jesus Christ died for my sins, and rose from the dead and dear Father I ask You to save me from these sins in the name of Jesus Christ Your Son. And you will have eternal life, and the greatest freedom know to man,
If the Son therefore shall make you free, ye shall be free indeed.
