All the tax collectors and sinners were approaching to listen to him.
Luke 15:1 CSB
Christians are doing their job right if sinners want to hear the message being taught. See here that they were coming to listen to Him. They may have heard of Him because of His miracles, but they wanted to hear His teaching, and kept listening due to the content of the message.
The Christian message should be of interest to everyone. This does not mean ears should be tickled. The message is not to be changed. But, the audience should be targeted. It is good to teach to a certain crowd or group if that group is in need of truth.
Heavenly Father, You are wise and loving. You know how to get the truth to those who need it. We but need to follow Christ in this. Thank You for loving Your world so much as to send Christ! In the Name of the Lord Jesus Christ I pray and praise You, Amen.
