"Thou therefore, my son, be strong in the grace that is in Christ Jesus." (2 Timothy 2:1)
In the Old Testament, "grace" (used 69 times) is often applied in the sense of personal favors or physical blessings. "For the LORD God is a sun and shield: the LORD will give grace and glory: no good thing will he withhold from them that walk uprightly" (Psalm 84:11). In the New Testament, however, the term (used 156 times) often seems to emphasize God's personal empowerment or the granting of His unique spiritual favor, as is clear in the wonderful passage Ephesians 2:8-9: "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast."
Once the saving grace has been given, the believer is expected to use that grace with victory in mind--confidence that empowers our spiritual life and witness. We are to be "strong in the grace that is in Christ Jesus."
Hence, we are to "be strong in the Lord, and in the power of his might" (Ephesians 6:10) as we wrestle against the powers of darkness that battle us unceasingly. Although "|we| can do all things through Christ which strengtheneth |us|" (Philippians 4:13), we must remember that those "things" include the entire spectrum of poverty to wealth and from hunger to satisfaction. God's grace is strong enough to counter every worldly circumstance.
We must remember, however, that even the greatest heroes of the faith endured intense opposition, seasons of pain and privation, and occasionally were tortured to death (Hebrews 11:32-38). God's strong grace is sufficient. "Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong" (2 Corinthians 12:10). HMM III
