according to the foreknowledge of God the Father, in sanctification of the Spirit, that you may obey Jesus Christ and be sprinkled in his blood: Grace to you and peace be multiplied.
But what Peter writes in 2 Peter 1:10 makes it clear that election is not a "fixed" matter. There he warns his readers to "make your calling and election sure: for if you do these things, ye shall never fall." There are some things the Christian must do to make his election "sure." In other words, election is not a "sure" thing; to make our election sure, we must add several things to our faith: virtue, knowledge, temperance, patience, godliness, brotherly kindness, and charity. He goes on to warn that if we do not add these things to our faith we are "blind, and cannot see afar off" (2 Peter 1:9).
