What is mental strength?
The mind is the part of a person that ponders, reflects, reasons, thinks, feels, and remembers. Therefore, mental strength is a group of qualities that make a person endure challenging situations and emerge without losing heart. Basically, mental strength is the set of positive characteristics that helps a person to handle tough situations.
The question becomes, as children of God are we called do do certain stuff so that we can become mentally strong? Many times we are given a list of things that we are supposed to do so that we can become mentally stalwart. In an article entitled 5 Characteristics of a strong mind, Michael Hyatt, says mentally strong people have five elements; confidence, courage, commitment, control and purpose.

If I could meet Michael Hyatt, I would like to ask him where does those elements come from? Can I ever do anything to become confident, courageous, committed, self-controlled and purposeful? Peter said in his epistle God has given us all things (not some things) that pertain to life and godliness. Does mental strength not pertain to life and godliness? If so, then God has given us. Paul told his protege, Timothy, "you have not received the spirit of fear (not confident, not courageous, not committed, not controlled and not purposed) but of power (an inherent miracle working power) and of love (an inherent expression of God's glory) and sound mind (inherent understanding and knowledge of God's work).
