1 Peter 5:10 But the God of all grace, He who has called you into His eternal glory in Christ Jesus, after you have suffered a little while, will Himself perfect, establish, strengthen, and ground you.
"All grace" refers to the riches of the bountiful supply of the divine life in many aspects ministered to us in many steps of the divine operation on and in us in God's economy. The initial step is to call us, and the consummate step is to glorify us. Between these two steps are God's loving care while He is disciplining us, and His perfecting, establishing, strengthening, and grounding work in us. In all these divine acts, the bountiful supply of the divine life is ministered to us ass grace in varied experiences. The God of such grace will perfect, establish, stregthen, and ground the persecuted believers after they have suffered a little while.
