It can be a scary thing to be told something like that, especially if one is not mature in Christ. Do not let this be a stumbling block to your faith in Him. Ps 119:165 Great peace have they which love thy law: and nothing shall offend them.
It might be worthwhile considering the things that she said in light of God's word for nothing happens apart from God's control. No one is perfect but we are called to spiritual maturity and to go on to perfection in Christ. Jesus is coming back for a church without spot or wrinkle - perfect church.
It is Christ who changes us by living through us as we daily take up the cross, deny ourselves, follow Him. Christian life should not be measured by how much we do for God but we ought to live in perfect obedience to His Word and will for our lives. We are to be changed from glory to glory into the image of Christ, as we yielding ourselves to be broken for Him so that the master potter can mold and make us into His vessels for His use.
I think it is important to know the calling that God has for your life, for God will certainly use you for His good pleasure. He gives a different measure of faith to all His children. He who has been given much, much will be expected of him.
It is the Holy Spirit who teaches us these things when we walk in the Spirit. He shows us how to live by impressing in us, what is expected of us to do, at each level of our walk with Him. The christian life is a upward climb.
It is a gradual process of learning the ways of God and attaining to perfection in Christ. The bible does also say to keep one's faith between oneself and God and whatever you do, do all unto the glory of God.
Your friend is not perfect. Just because she is able to hide her flows from you, does not mean that she can hide them before God. Anyway, I think people like that may be desperately trying to hide a flaw, or reaching out for something they are desperately lacking.
If other people are too busy looking at their perfection, maybe they won't see there vulnerabilities. Have you heard jesus talking of the log and the beam in the eyes, the republican and the pharisee? In Psalms 51, David said God is pleased with a humble spirit and repentant heart?
People like that are so busy seeing how far up the spiritual ladder they are above somebody else, that they are completely unaware that there is no foundation on their next step up- Satan pulled if off when they wasn't looking! They were too busy looking at your faults instead of theirs. Jesus is your standard- your friend should know that!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
