Comment:  The “most holy faith” Saint Jude spoke of refers to our belief in God Almighty and His son Jesus Christ, and in life everlasting in the world to come.  Since one cannot be on God’s side of favour without striving to measure up to His standard of righteousness, we must examine ourselves, making amends when mistakes are made and growing the qualities that makes us Christians indeed.  These qualities include diligence, faith, virtue, knowledge, temperance, patience, godliness, brotherly kindness, mercy, kindness, humility, longsuffering, forgiveness, charity, etc, (2 Peter 1:5-7; Colossians 3:12-14) Building up ourselves on our most holy faith requires that we keep piling up good thoughts and deeds upon one another, not mixing good deeds with bad ones.  The prophet Solomon states that the path of the just should be as a shining light that shines more and more until the perfect day. (Proversbs 4:18) A factor that makes some people unable to keep building up themselves in the way of God is that after sometime, they rest on their oars because they feel they have worked so much over the years. St. Paul says we should not do so. (Philippians 3:13, 14) He also exhorted: “As ye have therefore received Christ Jesus the Lord, so walk ye in him: Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving.” – Colossians 2:6, 7.
