if your, only look at the gospels ,then you miss the change,from new to old, because jesus was sent to a jewish people / nation.
and is wrote to us now, 2000 yrs like a history book. as in nothing changes when it down on paper.that dose not mean we cant learn from jesus or what he said or did, or spirital understandings. etc
when the holy spirit was given to us or who, are gentiles by birth was after penticost. so going back to the gospels to build law of moses back in to grace is pointless. again alot of post have echoed this.
4But when the set time had fully come, God sent his Son, born of a woman, born under the law, 5to redeem those under the law, that we might receive adoption to sonship.[19] 6Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba,[20] Father.” 7So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir.Galatians 4
so no longer are you a slave to law, but a son of god, and all that read the bible and pray to god/jesus have different understanding. this dose not mean we will all have the same understanding. because he teaching us as a father at a personal level. etc
