Acts 11:23 When he came and had seen the grace of God, he was glad, and encouraged them all that with purpose of heart they should continue with the Lord.
You can see where God is working and you can see where people are following Christ; there is a big difference in attitude, appearance and general demeanour of the people.
We are called to be effective witnesses for others; but this requires us being effective followers and disciples of Christ. It is then that people will see the difference for themselves.
It is then that people will follow with their hearts just as we do. Give it all to Christ from deep in your heart today.
