Relationships

When it comes to sharing the Gospel, how important is it to building relationships before sharing? Some say build a relationship before you invite them to church or before you share. But is that even right? I know that as a Christian I should live in such a way that my lifestyle will be ministry for those to see. But instead of beating around the bush, why not get straight to the point and share Christ. Jesus did it, but he also build relationships as he went along.

So help me understand this a bit better. Give me a little insight as to how I should go about this, cuz I wanna share Christ with the world and invite them to church.
