1 Corinthians 15:10 But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I labored more abundantly than they all: yet not I, but the grace of God which was with me.
Every one of us are what we are in the natural by our birth, by our training, and by our experiences. We are also something by the grace of God. Because of this, it is not unjust of God to require anything of us. Whatever God requires, His grace enables us to do it and makes us enough or sufficient for the obligation or responsibility (Acts 1:8, Ephesians 2:10). God wants nothing empowered by us. The work we do, there is grace for it. (See Acts 14:2-3.) I would not embark on any ministry or service without an understanding of grace, or you tend to do things in vain or in frustration to the grace of God. In the early church it was considered recommended and necessary equipment for fulfilling the work of God Acts 14:26; 15:40. God doesn’t call the equipped, He equips those He calls.
Since all Christians are given gifts of grace for service (Romans 12:6) and no one is given grace to sit or to do nothing. Grace supplies divine motivation and energy to do work for God in the Earth. It is described as the working of God in Philippians 2:13, “For it is God which worketh in you both to will and to do of his good pleasure,” and similarly in Hebrews 13:21, “Make you perfect in every good work to do his will, working in you that which is wellpleasing in his sight, through Jesus Christ; to whom be glory for ever and ever. Amen.” This working energy is for a purpose which is for doing the work of the ministry, “Ephesians 4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; 12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: 13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ.
