“Therefore, brothers, be all the more diligent to make your calling and choosing sure; for in doing these things, you will never stumble; for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you.” (2 Peter 1:10–11 LSB)  https://accordance.bible/link/read/LSB#2Pet._1:10

This chapter of the Bible is both a reminder of the salvation we have been given through the work of Jesus our God and an admonition to live out that salvation, proving its work in our lives, bearing fruit through our lives. Salvation, acceptance by God into His heaven and eventually His new earth, is made possible by God alone. Humanity is born ignorant and rebellious against God, from birth we ignore God and disobey His commands. This helpless and hopeless state of being is saved by God through His past work at Calvary and His current work by His Spirit in our hearts. At Calvary God came to earth as a man, lived a perfect life, so He could offer Himself as a sacrifice, the punishment, for all of humanity’s evil against God. The crucifixion was the sacrifice made and accepted by God the Father proven through the resurrection from the dead when Jesus appeared before more than 500 to assure them that His work was complete. Acceptance by God is now possible for humanity by appropriation to them of Jesus’ perfect life and because of His payment for humanity by His sacrifice on the cross. We then, who have been awakened by God to know God in Jesus the Savior, are to live lives reflecting the life of Jesus. We are to be diligent in our efforts to please God and to reveal God so that others whom He is working in, can see God and hear God in order that they too might know God in Jesus the Savior. The means of God for revealing Himself is through His people who come to Him through His Spirit and His word in order to know Him and be empowered by Him for making Him known in the world. God has saved us, let us prove our salvation by living holy lives and telling all humanity about the great love of God demonstrated by the work of God in Jesus the Savior.
