If we look at Hebrews 7:1-28 we can understand that Christians are no longer to have anything to do with the lesser covenant, that it cannot perfect us while Jesus can...
If we look at 2 Corinthians 3:1-18 this is driven home, going so far as to say relying on texts - especially those of Moses - dulls the mind and veils the heart...
If we look at Ephesians 2:11-22 we find that by dropping Jewish commandments and regulations we are bridging the divide between peoples...
Essentially the whole of Galatians is nothing but commentary on this topic...
Why is all of this ignored today?
Why is Christianity not about perfecting love, but rather continues to cling to condemnation?
We see in places like John 17:20-26 that the goal is complete unity, the same glory Jesus had.
We see in 1 John 4:7-21 how to prepare for judgement, becoming as he was.
Where is any of this in modern Christianity?
Christianity is all about perfecting love, especially the teachings of Jesus. But you must remember that the Bible is not the work of God. It is the work of frail human beings who are not all always consistent to the theme of love. Also, you cant fill the pages of a thousand page bible with just love teachings. you must also talk about the various judgments of God, which are not opposed to love (for God) but may be seen as opposed to love by imperfect human beings. So my suggestion would be to not read the scriptures too much as it is the work of imperfect people like you and me, but to stick to the message of love and sacrifice as symbolized by the life and death of Jesus.
