"Everyone in your life is either pointing you to Christ or trying to discourage your relationship with Christ"
I'm going to have to break that down, because this thought, while often true, doesn't have to be. As Christians we love fellowship with the brothers and sisters that God has put in our lives; our church family, our pastor, our "blood" family, friends on Facebook and even some co-workers. When we think of those that point us to Christ we think of those people and rightfully so, they know Christ as well, our spirits bear witness to one another and we are greatly encouraged with interactions. So, the first part of the quote is a given. But what about the second part?
Along my walk with Christ there has come others that are seemingly there to try and discourage my relationship with my Lord. They, too, could be close friends, professing Christians, family members, co-workers or even the cashier at the grocery store. Sometimes they may call you a "fanatic" or "Jesus Freak" or "Holy Roller", but all in an attempt to try and make you look odd or weird because you actually follow what scripture says; that you love God and love people. This can get you down because we, as humans, still crave acceptance and rejection is not what anyone wants or desires. They offer worldly "fixes" to your problems and do not point to God. What do we do then? Usually lay off a little bit, maybe turn down the volume knob from 11 when around those people. But, I say "Why?". Why would we want to snuff, maybe the only Light these people might ever see? Why allow them to think that a relationship with God should be based on their views or any other view not found in scripture but is rooted in the world view?
I suggest that when these people are placed in our life that it is not coincidental. Instead of allowing them to manipulate our actions, words or deeds when in their presence that we do the same things that we do when we are within the walls of a church building - Praise God. Do not let an attack drive you from Christ, but let it fuel an increased dependency to run TO Christ. Take it as yet another reason to seek His face, to lift this lost person up that they may sing the same praises to God as you.
Remember that we are not fighting against flesh and blood, but against things in the spiritual realm. Most people are under the influence of this world and their views are based on the morality (or lack of) that is set forth by people. Now, I'm not saying all people are possessed by demons, but I do believe a lot are. I believe those that are not have been lulled into the creed of "Do what thou wilt shall be the whole of the law", or more easily understood as "Let me live my life the way I want, you live your life, whatever feels good for you is perfectly fine", which I translate as "There are no absolutes and everyone makes their own truth about everything". This of course, is not valid if you actually follow the Bible and God as Scripture reveals how a follower of Christ actually is.
Society says that all views are valid, until you start speaking in absolutes. This is self refuting because that statement is an absolute statement. This kind of thinking is better known as "post-modernism", which has infiltrated the "church" (lowercase c). I like to say it has infiltrated the perceived church, or what the world sees as the "church". Now that the World sees professing Christians say that we must question everything in the Bible, that the Word of God is invalid in some areas, that "sin" is not really sin and then see other's say that we must still follow the Word of God and actually still do, they are seen as "radical fundamentalists" or fanatics. I'd just say that they are actually Christians that are still seeking to follow Jesus Christ.
Back to the subject at hand, sorry for the rabbit chasing. Christian! Don't let this world discourage you from a true relationship with God. Seek people that can be a mutual edification between you and them, plant yourself in a true Church Body that loves and seeks after God in all things. Ground yourself in the Word of God. Purge yourself of as much of this world as possible. Seek Jesus Christ. Let the World be a constant reminder of how much you need God, in every step you take, every breath you take, every word you say. Let those that could be discouragement instead be another reason to praise God and call upon Him. Use this world as encouragement, to seek God instead of something that will drag you down and cause spiritual decline.
Seek God in all things. Praise God in all things. Speak of God in all things. Live to God in all things. Allow God to use you to further His Kingdom. Do not conform to this World and allow it to mold you. Let go and let God.
(I just did a fast search and did not find anyone else that had said the original quote of this post. This thought has been building in me over the past few weeks as a current trial has been developing. I have seen God greatly encourage me through the Body, I have heard worldly advise and I have seen attacks from people that claim to have the same Spirit residing in them as I do. I have let the latter affect me, but no more. I know my God is faithful and my God is able. I know that God fights for me and I know that all things He allows in my life are for my good. He has placed His yoke upon me and is carrying my weight He is directing my path and He is ordering my steps. I have His promises that He will do only good for this situation, that I am not being punished for anything because Christ bore ALL of my punishment on Calvary. I need only trust that He is working all things for my good and just follow His lead. He is in control and I rest in that.)
