But grow in grace, and in knowledge of our Lord and Savior Jesus Christ. To him be glory both now and forever Amen (2 Peter 3:18).
The word "grace" is from the Greek "charis" and it refers to the divine influence in a human heart, which reflects on his outside, producing favor, beauty, goodwill, loveliness and ability. In other words, when "grace "is working in your life, there's just something about you that cause favor and glory to abound in your life.
For example, when the Lord Jesus was a child, the Bible says he "...grew, and waxed strong in Spirit, filled with wisdom: and the grace of God was upon him" (Luke 2:40). It made Him, even as a child, to have favor with God and man (Luke 2:52). In the Book of Acts, Barnabas went to visit certain brethren and "...when he came, and had seen the grace of God, was glad, and exhorted them all..." (Acts 11:23).
What was it that Barnabas saw? It wasn't a light beaming out of their heads-He saw the beauty of God; he saw that things were working out excellence in the lives of these brethren,
Grace is the power of promotion; it is the thing that causes your life to move from one level to another and that's why the Bible says we must grow in it. The good news is that every child of God has received grace in abundance (Romans 5:17), but the degree to which you let it reflect is up to you. The more you fill your heart with God's Word and have the Holy Spirit work in your life, the greater that grace will shine forth on the outside.
You can and should increase in that outward reflection of the glory in your spirit, to such an extent that others would take notice. They might not be able to explain it, but they will not be able to deny that there's just something excellent and beautiful about you.
