Gospel in Words and Gospel in Deeds

Jesus ministered in word and in deed. He said His works testified of Him.

The Gospel is not only communicated by words but also by deeds. Preaching, talking, apologetics, discourse, conversations exemplify the Gospel in words. But, the Gospel can and is expected to also be communicated by deeds.

One may confess with his mouth that Jesus is Lord (Rom.10:10). But, they may deny the Lord by their works.
They profess to know God, but in works they deny Him, being abominable, disobedient, and disqualified for every good work. (Tit 1:16)
Many times, the Gospel is more effectively communicated with great conviction by actions, without words.
Wives, likewise, be submissive to your own husbands, that even if some do not obey the word, they, without a word, may be won by the conduct of their wives, (1Pe 3:1)
