I don’t think it is good to look for signs.
I believe that the Holy Spirit convicts each soul of its sins to degrees and degrees again because each man has a measure and it is no-one else’s business who has what measure and to whom God has given what and that men cannot judge one another nor even themselves.
The witnessing of the Gospel lived by the prayer of our lives is not to condemn men because Jesus Himself condemned no-one (Jesus promised the Good Thief eternal life, but He did not condemn the other thief). By living the Gospel and therefore preaching the Gospel in the prayer of our lives we bring light to the world as Jesus told us to do, not to condemn but to spread the Light of God into the world.
Feelings are no indicator of grace either. A soul may feel no internal spiritual joy though they display every joy outwardly. A soul may feel totally dry and experience nothing at Mass other than living faith in darkness. God may even effect a spiritual distaste for all things holy and God has good reason for this.
Individually we are each convicted of our sins by the Holy Spirit and we can only discern for ourselves whether we are in fit state to receive Christ Jesus into our souls. And still there are pitfalls here. So unless we have murdered someone (or something to that degree then we had better seek confession for those who are within the faith and faith convicts them to that by the power of the Holy Spirit - as for others they must do the best they can do within what their conscience convicts them of , as faith is a gift) we are better to ask Jesus to cleanse us of all venial sins and receive Him to be transformed in Him.
If grace only ever brings us spiritual satisfaction then truly I believe it is not grace because grace leads to the cross. And grace is Love.
I cannot say I or anyone else is in a state grace but I do believe that God will put us into it if it pleases Him, to say otherwise is to condemn. I can only say that I am a sinner and desire to be a saint. None can say that they have not sinned and no man can put themselves in a state of grace.
We will only ever truly know the state of our souls when we come before the Lord at the end of our lives. Our Blessed Mother came before the Lord when the Holy Spirit overshadowed her in perfect union with God and only then she learnt of the state of her soul. For now all we can do is pray, endure in faith, persevere, hope, trust, strive in the practise of virtue and most of all, love God and neighbour and grow in love of the cross. Desiring and praying for a holy death and to receive the Last Rites.
‘Lord have mercy on me for a sinner I was conceived’ Hold onto to that in faith and don’t worry about the state of grace because if God chooses we can be within it within the blink of an eye. However God’s work of grace takes a lifetime.
If you post this wondering about yourself, then you cannot know the answer, but strive to live the Gospel and embrace God’s inspirations of grace. If you post this wondering about others, then it is none of your business! - ‘What is it to you what I do with him?’ (Jesus speaking to Peter about John)
The rich young man thought he was rich in the ways of God only for Jesus to point out his poverty. The Pharisee sung his own praises before God and thanked God he wasn’t like the tax collector, only for Jesus to say the tax collector was more at rights with God for asking for mercy as he was a sinner…be careful and cling to the knowledge you are a sinner like everyone else and thank God for His kindness and mercy to you and to all people.
