This was far more than the need to tie a string around the finger, and certainly not something that should be so soon forgotten that it no longer was having an effect on the lives of the dispersed tribes. The message of the Messiah, Jesus, had reached the “scattered tribes” and effected a transformation in their beliefs. Somehow coldness had penetrated these new found truths and Peter is writing to awaken them from this blindness or short-sightedness.
Once the message of Christ had been presented, which Peter said: “those who have received the faith of the same kind as ours, by the righteousness of our God and Savior, Jesus Christ”, would also impart “Grace and peace” in the knowledge of God and of Jesus our Lord” (2 Peter 1:1,2), should understand that what transpired was “His divine power had granted to us, everything pertaining to life and godliness through Him who called us by His own glory and excellence. For by these He has granted to us His precious and magnificent promises, so that by them you may become partakers of the divine nature, having escaped the corruption that is in the world by lust” (2 Peter 1:3-4)
When one receives Christ as his Savior and Lord, and that by the way is a personal experience of recognition that they are a sinner, and Christ died for their sin, they accept the fact that His blood alone can atone for their sin. They are acknowledging before Him, the triune God, that to be the case, they personally invite Him to be their Savior and Lord. At that moment, as we read previously, they (you or I) became “partakers of the divine nature”.
If one reads on, they quickly discover that new nature leads us to a new life of moral excellence which adds knowledge, self-control, perseverance, godliness, brotherly kindness, and love. For, if these qualities are yours, and are increasing, they render you neither useless, nor unfruitful in the true knowledge of our Lord Jesus Christ.” (1:4-8)
It is after what God/Jesus Christ has imparted to us, His “divine nature”, that we are able to add those qualities. In fact, we are reminded that we should not become short-sighted; and in our adding these things to our daily living and practice, we are guaranteed not to stumble.
Peter adds this REMINDER: “Therefore I will always be ready to remind you of these things, even though you already know them.”
