“It is the Spirit who gives life; the flesh accomplishes nothing. The words that I have spoken to you are spirit and life.” John 6:63, ISV

The flesh accomplishes nothing, doesn’t mean it cannot come across as busy and occupied, but at the end its accomplishment would be nothing.
Cue the man who’s living life or seeking to resolve a situation based on his carnal observations, he could try all the methods and do everything he’s instructed to, but at the end, he would have accomplished nothing.
Don’t make worthless investments in life:
“For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.” Galatians 6:8
Make spiritual investments, get to God’s word and be busy about knowing God and keeping his word, through your knowledge of him, grace abounds towards you and that grace would distinguish you and the kind of results you enjoy in life:
“Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord,” 2 Peter 1:2
