Salvation provides all the necessary qualities. Salvation is by faith, and faith is given to us by a sovereign God. A measure of faith was given to us as part of God's gift of salvation. Our salvation brings us into the true knowledge of God and of His precious Son, Jesus Christ. Salvation provides everything necessary for godly living, which we see in 2 Peter 1:3, "...His divine power has granted to us everything pertaining to life and godliness..." It is this salvation that has enabled us to become partakers of the divine nature. Verse 4 says: "...having escaped the corruption that is in the world by lust." The two go together. We've become partakers of the divine nature, and God's character is manifested in us, because we have escaped the wickedness that is in the world.
