You are reading into universal salvation what it is not..
It still requires repentance and forgiveness through the Grace of God. In this world or the next.
It is interesting that you jumble Old Testament and new Testament references. The Old Testament refers to the the Jewish Covenant with God. The new is the summation of what those later authors believed.
What did Jesus say at Matthew 12 v 32; Mark 3 v 29; Luke 12 v 10 about this world and the next world? but that whosoever speaks against God's spirit it would Not be forgiven him, neither in this world, neither in the world to come. What does Hebrews 6 vs 4-6 also say ?
Jesus often prefaced his statements with the words, " It is written...." meaning already written down in the old Hebrew Scriptures. Jesus based his teachings on his logical reasoning on the Hebrew Scriptures. Before the Exodus the Hebrew Scriptures were Not part of the Constitution of the Mosaic Law contract with the nation of ancient Israel. Genesis is Not part of the Mosaic law. For example: God's everlasting covenants or contracts with Abraham and Noah are permanently on-going.
Unlike other religious books, the Bible is chock full of cross-reference parallel verses and passages thus showing the internal harmony among its many writers.
