Rom. 1:17 This Good News tells us how God makes us right in his sight. This is accomplished from start to finish by faith. As the Scriptures say, "It is through faith that a righteous person has life."
We tend to get this verse wrong. We start out on our journey with God by faith, but then we get the idea that we have to take over and work our way into heaven from there. We tend to want to make ourselves righteous instead of trusting Christ to be our righteousness. The Good News makes it clear that it is God who makes us righteous, not ourselves.
Salvation is proven by our works, but it is never achieved by our works. Christ alone is our righteousness. He alone can make us pure in heart and keep us pure. He alone will get us to heaven. The sooner we believe and accept it, the sooner we will live in victory and peace.
When we try so hard to be pure before God on our own, we struggle mightily. We are weak in the flesh and cannot overcome sin without Christ's help, no matter how hard we try. We are no match for Satan or his demonic force. We can live in victory when we live and trust in He who has overcome Satan. Only in Christ are we able to relax and live in peace. It is by faith alone that we receive eternal life and it is by faith that we will see our faith give way to sight in heaven. From start to finish, we are righteous before God in Christ alone.
