Loving Without Conditions

Why is it that Jesus' first and most direct teaching gets so little attention? Why is it that the focus for many churches tends to be on other things, such as: history, politics, traditions, rituals, the state of the world, finances, converting people, the end of times, etc. without placing emphasis on the teaching of Christ before them? It would appear that the a priori condition for success in all the avenues that the church dwells in would be abidance in the Lord. That's what the teaching of Christ does. It aligns us with the patterns of Divinity, expressed through us as unconditional love.
