Warren Wiersbe. I rely on his commentaries just about every week as I prepare to serve in Sunday School. This week it is James 2.  And Wiersbe wrote this:

Here are some questions we can ask ourselves as we examine our hearts:
1. Was there a time when I honestly realized I was a sinner and admitted this to myself and to God?

2. Was there a time when my heart stirred me to flee from the wrath to come? Have I ever seriously been exercised over my sins?

3. Do I truly understand the Gospel, that Christ died for my sins and arose again? Do I understand and confess that I cannot save myself?

4. Did I sincerely repent of my sins and turn from them? Or do I secretly love sin and want to enjoy it?

5. Have I trusted Christ and Christ alone for my salvation? Do I enjoy a living relationship with Him through the Word and in the Spirit?

6. Has there been a change in my life? Do I maintain good works, or are my works occasional and weak? Do I seek to grow in the things of the Lord? Can others tell that I have been with Jesus?

7. Do I have a desire to share Christ with others? Or am I ashamed of Him?

8. Do I enjoy the fellowship of God’s people? Is worship a delight to me?

9. Am I ready for the Lord’s return? Or will I be ashamed when He comes for me?

To be sure, not every Christian has the same personal experience; and there are degrees of sanctification. But for the most part, the preceding spiritual inventory can assist a person in determining his true standing before God.

“Search me, O Lord, and know my heart: try me, and know my thoughts: and see if there be any wicked way in me, and lead me in the way everlasting” (Ps. 139:23–24).

Such important questions, the most important questions, we must ask ourselves.  Just saying . . .
