2 Peter 1:3 According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue.
Our Lord Jesus has given us everything we need that relates to life and godliness. His divine power has granted all of it, so that we might have no doubt about this promise. The power of Christ overcomes all temptations to sin, all lies of Satan, and the looming shadow of death. It is not simple, natural, or even possible, for us to believe this promise, because we are inundated with sin and evil around us and in us.
That is what we see. 1) It is easy to agree with the accusations of the devil (I am a guilty sinner); we need the power of God to believe the overcoming Word: ”There is therefore now no condemnation for those who are in Christ Jesus.” 2) It is easy to give in to the temptations of the world (I go along to get along); we need the power of God to believe His present help: ”God is faithful, but with the temptation he will also provide the way of escape.” 3) It is easy to give up trying to change the sinful flesh (I can’t do it); we need the power of God to believe His victory: ”Who will deliver me? Thanks be to God through Jesus Christ our Lord.” 4) It is easy to resign ourselves to death (we’re all going to die): we need the power of God to believe the victorious promise: ”Death is swallowed up in victory.”
Incredibly, we can and we do live a life of godliness, because He has “called us to glory and virtue.”
