The three keys to perseverance Paul lays out in Romans 15 are 1. To react to challenges victoriously, to have perseverance, one must have an outward focus, and not be selfish. But recognize others have a claim on us to build them up in the Lord. 2. Be strengthened by the inspiring examples of faithful followers of God preserved in Scripture and 3. Let God speak to our thinking through his people and through his Word, so that we can come together with one mind and one purpose.
