Acts 9:20. "Without delay he preached in the temples that Christ was the Son of God."
Some have known the Lord for many years but do not come forward to tell others about Him and serve the Lord. But here the verse says that as soon as Paul knew the Lord "without delay" he preached in the churches about Christ.
If we have the true love of God and the joy of salvation, we will always have a motivation to do something for the Lord. With the inspiration of the Holy Spirit, we shine and are useful to other people.
We see in the scriptures that heaven rejoices when someone is saved on earth. Perhaps there are some who are reluctant to tell about the Lord, so from today, rise up and shine for the Lord without delay like this Paul. Amen.
