One of the major signs that someone needs to be revived is a lack of concern for the lost. In David's psalm of repentance, Psalm 51:10-13, he says,
Create in me a clean heart, O God, and renew a steadfast spirit within me. Do not cast me away from Your presence, and do not take Your Holy Spirit from me. Restore to me the joy of Your salvation, and uphold me by Your generous Spirit. Then I will teach transgressors Your ways, and sinners shall be converted to You.
When David says, Renew a steadfast spirit in me…Restore to me the joy of Your salvation, he is saying, "God, revive me, restore me, renew me." One of the fruits we find in a heart that has been revived is a desire to see others converted. Then I will teach transgressors Your ways, and sinners shall be converted to You.
When a person's spiritual life wanes, there is very little thought and very little action aimed at reaching the lost. Yet, someone who has been revived and is spiritually healthy will be actively engaged in the evangelization of the lost.
Read carefully these words from Elton Trueblood, a Quaker scholar. He said, "Evangelism occurs when Christians are so ignited by their contact with Christ that they in turn set other fires. It is easy to determine when something is aflame. It ignites other material. Any fire that does not spread will eventually go out."
When you are spiritually revived, you will think about the spiritual state of the people that you rub shoulders with every day. It is inevitable that when your heart is revived and close to God, you will have a concern for the lost.
