Philippians 1:6 Should this verse be used to Guarantee Security of Salvation

"Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ." This verse has been used by many as an exhortation to those who are finding it hard to be obedient to God. But is that a proper interpretation of this passage? Listen as we comb through this epistle, and a few of Paul's other letters, to see if this verse is being applied properly. Should we exhort or encourage someone who is living in sin with these words from Paul.
