"I am a sinner saved by grace" vs. "I am made righteous through the blood of Christ."
Hello justbyfaith,
Everyone is a sinner, who has had their sins paid for.
On the cross by the Lord Yeshua Christ, whom was resurrected three day later by God after being buried and seal in a tomb and dwelling in the heart of the earth for 3 days - in (she'ol/hell/grave) which Death, and Satan were conquered over at the resurrection of the Messiah.
Anyone who has a God given measure of faith to a person, that person is more than likely saved and has the spirit living with-in them.
Many people may struggle in faith due to life experiences, from growing up, family matters, school, friends, relationships, girlfriend/boyfriend wife/husband.
All the worries of the normal life can always place mental stress on us all the time from all the constant worry and everything about tomorrow, or whatever it may be going on at that time.
The only solution is to believe and turn towards God when you start hearing or reading more about the truth of the Gospel that leads a person to learning how the Lord Jesus Christ is the way, the truth, and the life.
The question is does a person desire to know truth in their life?
Learn about the Lord, whom created this world, and all of us people, who died on the cross, and everyone laughed and mocked him, always trying to figure out ways to trip him up, and lying about him to others, and saying he is mad, or he is of the devil.
Here is my stance on the questions.
We are saved by grace through faith from God that is given from trusting and leaning on God our Father and the Lord Jesus Christ, and continue to learn about them, and make the choice to place them first, and love others. We are still sinners (not perfect - we can be mature (perfect) in our eternal life (Faith) with God and the Lord - by building relationship with them and trusting them to help us in our life!
We are transformed however from sinners -> We are transformed in to children of God (John 1:12) through believing on the Lords Yeshua Christ name.
