No, I do not believe that good works done to others are more valuable to God than preaching and therefore people who do good works are not more spiritual than those who simply preach? Only God can say who is spiritual and who is not. There should be – must be a balance in our witness. In the Gospel of John chapter 5 and verses 31-39 Jesus said that He has a Fourfold Witness: (1) John the Baptist; “John… has borne witness to the truth” (2) The works that Jesus did, “the very works that I do — bear witness of Me” (3) The Father, “the Father Himself, who sent Me, has testified of Me” (4) The Scriptures, “the Scriptures… these are they which testify of Me”
A person is not saved by good works, but once saved the Christian is to perform good works. (Ephesians 2:8-10). One of the many works we are to perform is preach the Word. That is so important because it is the power of God unto salvation. (Romans 1:16) For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek.
