I’m finally moving into Timothy. We know that the books that Paul wrote are God-breathed, but if you needed confirmation, you would find it in the greeting at the beginning of 1 Timothy.
To Timothy, my true child in the faith: Grace, mercy, and peace from God the Father and Christ Jesus our Lord. 1 Timothy 1:2
You’ve got to wonder who would have the nerve to write a greeting from “God the Father and Christ Jesus our Lord,” without permission from God himself. Paul was God-fearing, and he wouldn’t compromise his position in the Lord by speaking for him unless he knew that God had allowed it. If you doubt that the New Testament scripture is an institution of God, he gives us confirmation in this verse. Ultimately, the Holy Spirit is our companion when it comes to holding onto our faith in God and his Word. If you have any doubts, I suggest you have a conversation with God because your foundation in Jesus may be compromised and it may be possible you don’t know him.
