Insight: No matter what you think God says you are good enough. In fact, you were created in His image and He sent His Son to die on the cross for your sin. My challenge to you is to focus on what God sees in you and not what you think about yourself. I myself have had these thoughts pretty much my entire life and a friend actually gave me some Scriptures which have really helped me, so I am going to share them with you as well.
Issue: I have been divorced and I am in a new relationship. Christians are telling me that I am committing adultery and so is he, so does God expect me to be alone for the rest of my life because I made a mistake?
Insight: I believe that God hates divorce because it tears apart the very fabric of the family entity that God created. Divorce hurts not only both people in the marriage but also any children that were conceived. God hates to see His children in pain and this is why he hates divorce.
Issue: I find it really hard to trust God. I have trust issues with people I can see let alone God who I can't.
Insight: Believe it or not this is an age old questions. In the days of Moses (read Exodus, Leviticus, Numbers and Deuteronomy in the Old Testament for the complete story of Moses) the Israelites also had a hard time trusting a God they could not see, even with the miracles that God had performed for them. So first of all you are not the only one in that boat. I too have had my trust issues with God.
Issue: There are days I just do not feel I deserve God's grace. I find myself engaging in gossip, purposely evading the truth, being harsh with family, ignoring friends, etc. I feel like I am never going to be good enough for God to love.
Insight: God does not love us based on how good we are, if that was the case none of us would be able to receive God's love. "for all have sinned and fall short of the glory of God," Romans 3:23. God loves the entire world. There is nothing you can do to make God love you more and there is nothing you can do to make God love you less. "But God demonstrates his own love for us in this: While we were still sinners, Christ died for us." Romans 5:8. No matter how unworthy you may feel God gave us his grace not based on our performance but on His love and compassion for us.
Issue: I am not looking forward to Valentine's Day, since I will be facing it alone again. I find that every year I dread February more and more.
Insight: We all have people in our lives that we love. Why not focus on these people on Valentine's Day. Take a sibling or parent out to dinner. Go out to a movie with a friend. I look at Valentine's Day as a day to show how much you love the people in your life. It doesn't even have to be a material gift, just give someone a call, or a note of encouragement. Little things mean a lot more than you may realize.
I strive to help others by being a safe place for others to ask questions and pose issues they face.
