If we like to say I have a faith , you can not say faith if love is not there. Especially in the Jewish Christian Muslim sharing the Old Testament.
It is something that everyone knows about what is already being said.
Still want to say it again.
A law teacher asked Jesus. "Whose command is the most important?"
Jesus answered like this. "Lay your Lord your God with your heart, your soul, your thoughts. "
This is the most important, the first command.
The second is similar to this, "Love your neighbors to love yourself. "
The whole of the law and the prophets are on these two commandments. "
Matthew 22: 36.40
Deuteronomy 6 · 4-15
Listen, Israel. The Lord our God is the only Lord. Love the LORD your God with all your heart, with all your soul, with all your strength.
Leviticus 19 · 17-18
Do not hate your brothers in your heart. Praise your brobers frankly. Then you will not bear his sin. Do not take revenge. Do not hold a grudge against the people of the people. Love your neighbor as you love yourself. I am the Lord.
