" I thank my God always concerning you for the grace of God which was given to you by Christ Jesus, that you were enriched in everything by Him in all [a] utterance and all knowledge, even as the testimony of Christ was confirmed [b] in you, so that you come short in no gift, eagerly waiting for the revelation of our Lord Jesus Christ, who will also confirm you to the end, that you may be blameless in the day of our Lord Jesus Christ." 1 Corinthians 1:4-8 (NKJV)
A testimony is interpreted by many as an experience of a thing, place, or person; an account that is given in a court of law. This subjective understanding leads to God being presented as the God of our experiences whereas HE IS not. The testimony of Christ in our lives is not related to our experiences with the gospel. To believe so, will imply that God is only God because of His dealings in our lives. What makes His testimony perfect through the mouth of an imperfect Man is when we see Him as the ULTIMATE such that our witness of Him is no longer based on personal experiences.
The testimony of Christ is related to our encounter with His person. In Him, we have received everything that we could ever testify about and these things are found inwardly. Paul speaks about the testimony of Christ as being our PERSUASION of His work in us. It is what God thinks of Christ and what He thinks of us because the work of Christ. God confirms Christ's testimony in us and when we BECOME persuaded of this confirmation, we have the confirmation of God about us. His testimony clothes us with ALL riches, in all utterance and knowledge. Our testimony is derived from Christ, He is our assurance.
In this excerpt, Dr. Annie Smith reminds us of the testimony of Christ in us which enriches us with a consistent readiness of speech when we live, persuaded of the perfection of His work in us. This insight gives us practical steps to always walk victoriously irrespective of temporary feelings and situations in our lives.
