Psa 105:4 "Seek the Lord, & His strength: seek His face evermore."
You'll be amazed to know that in the Amplified Bible, "His strength" = His might & inflexibility to temptation.
My, this sure is one powerful definition of the word "strength" I never knew the Bible was refering to!
God's strength is His might & inflexibility (& intolerance) to temptation. To find your strength in the Lord is to lay hold of God's might to stand firm in the face of temptation, not flinching even a bit because this strength is intolerant of temptation.
