Actually, when I posted this there was no pride in my heart whatsoever. Nor was I trying to elevate myself. I am sorry if it sounded that way, but you guys don't know me so you don't know what I am really like personally. I have hardly ever been arrogant in my life.
I guess I just have a hard time understanding someone else who does not share the same concern for the lost that I do. I witness because I have genuine concern about others.
Maybe something that will help you is to know that God uses each of us in different ways for His kingdom and glory and also that there will be rewards in heaven for things that we do.
However, you need to see clearly that each of us is on our own path with God. Some people do seem to be a little more mature in Christ, but that God is working in all of us. What you need to do is look at other strengths in Christ that your mom may have and is Christ working in her life.
Now sometimes when God works in someone's life those things are plain for us to see as human beings (ie. they stick out like a sore thumb and we recognize and see them immediately) but some of the things God works on us are internal. One example may be forgiveness or us getting past a sin we have struggled with for a long time and really gaining ground on not doing that sin as much or realizing that we need to change something.
But, for you to take one aspect of your life, such as witnessing since you brought it up and compare your Christian walk with hers, on something God has called you to do (as you believe you have been called) is somewhat saying that God calls us all to the same exact thing in the same way.
God doesn't do this. Someone who has had a great struggle, I'll use alcholism as an example, can get through to an alchoholic in a way that someone who has never been an alchoholic has not and cannot.
The same with drug abuse, or sexual abuse or someone that stuggles in their Christian walk with inappropriate content or coveting.
We all have our struggles and you are being judgemental by saying your mom should be just as you are.
Some people just aren't witnessing kind of people. They find it very hard to be extroverted or to approach people, but these same people may never need to say a word if there lives reflect God. Many times non-Christians talk about how they do not see many Christians that there lives are changed, so you do not know what witness they are to God's kingdom or how whomever they are may be an example to others.
As Paul says that he and Apollos water, but God brings forth the growth. So we all water in our ways and I believe that God brings forth out of our deeds His glory.
There are other ways that someone can be a witness to Christ not just verbally speaking to people. Maybe you should encourage her or try to help her do other things she may be more comfortable with. Maybe you have gotten to a place where you have been so combative with this subject that now she is turned off to it and not listening anymore.
You need to try another approach and be loving and helpful and not judgemental.
