If you struggle with grace and believe you must “work” to earn and/or keep your salvation, consider what the author of Romans in the New Testament of the Holy Bible preached about the matter…
Paul (formerly known as Saul of Tarsus) was a master theologian and one of the most prolific epistoleans of the New Testament after his conversion. He was born a Diaspora Jew, doggedly adhering to Jewish tradition, but also held Roman citizenship, which made him uniquely qualified to intelligently speak with Jews and Greeks alike. This former Pharisee and persecutor of the church was the student of Gamaliel, one of the most notable teachers of Jewish laws and customs in the 1st century.
He had participated in the stoning of Stephen, and had relentlessly tried to destroy the church of God because they believed Jesus was the Messiah. By Paul’s admittance, he had been just as zealous for “the traditions of Judaism” as those who were followers of The Way. It wasn’t until his blinding (literally) personal encounter with Jesus on the Damascus Road that he was forever changed.
Paul’s conversion from Judaism to Christianity was so profound that he spent the rest of his life explaining the difference between righteousness based on the law, which he had sought in his former life and righteousness based on the death of Christ, which had true power to transform a life and set one’s standing right with God. The persecutor became the persecuted. The Pharisee became a humble follower of Jesus.
In Galatians he confirms that the Gospel he now preaches was not taught to him by any human, but rather a direct revelation from Jesus Christ Himself.
If there was ever a person who understood forgiveness and righteousness imputed to someone based on grace and not works, it is Paul.
I encourage you to read the entire chapter of Romans 4. We are blessed if we are forgiven, with our sins covered, never to be counted against us.
