"Therefore being justified by faith, we have peace with God through our Lord Jesus Christ." Romans 5:1
If you have faith that Jesus is who He says He is and that He has paid the penalty for your sins, even the smallest morsel of faith, you have been justified; pardoned, reconciled to God.
You are God's child and the recipient of all that was created for you. Even though what you inherit during your lifetime is not all that God has planned for you, what is available, now, is too big and too wonderful to measure. You have been justified; not you are going to if you do this or that. It is important to believe the WORD of God, for without faith you cannot see clearly what God has already done for you, nor what is ahead.
You are justified and you are at peace with God. So why don't you feel that way? It is in your thinking. If you don't know without a doubt that you are justified by God and at peace with God in every way, you have been conditioned by years of false teaching and some (self inflicted wrong thinking for your own so-called benefit). What a waste to live below your God given, God breathed potential.
You need to believe what God says and not let anything that contradicts it even enter your ears. If you were to start believing God for all that He speaks to you, you would feel at peace with God. The only thing you would loose is the baggage you have been carrying.
