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.”
God’s call is expressive of His nature; consequently when I receive His nature and hear His call, the voice of the Divine nature sounds in both and the two work together. The Son of God reveals Himself in me, and I serve Him in the ordinary ways of life out of devotion to Him.
From Galatians 1:15-16: “But when God, who had set me apart before I was born and called me through His grace, was pleased to reveal His Son to me, so that I might proclaim Him among the Gentiles.”
