Through the power of the Holy Spirit, believers have the ability to endure difficultly and accomplish whatever the Lord calls them to do.

From 2 Corinthians 3:4-6:  “Such is the confidence that we have through Christ toward God.  Not that we are competent of ourselves to claim anything as coming from us; our competence is from God, who has made us competent to be ministers of a new covenant, not of letter but of spirit; for the letter kills, but the Spirit gives life.”
