It is probably well near time that we developed a bit of maturity and realized that there will be no one name and no one qualifier that will speak identically to all people. So you might have a hard time with Master or Lord. So what? I don't and that is how I address God. I might have a problem with however you choose to identify God. So what? If it is what works for you then go for it. I can have a relationship with God even if yours is dramatically different and if your relationship with God suffers just because you can't control how I address God your biggest problem is not your relationship with God but you desire to control me.
I love this, but what if someone sees God as a violent vengeful God and thus believes that they are doing Gods will by forcing others to convert, should we speak out against this or are we desiring to control others just as much by insisting that God is love?
Eg: God says not to kill/murder in the ten commandments but in the same breath kills 3000 people for worshiping the Golden calf.
How can we ignore this side of God by insisting He is all loving?
