2 Corinthians 12:9-10 – And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. 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. (KJV)
I don't remember much from my advanced high school math classes. Some would argue that they have been of little use in my real life. What they don't know, though, is how often I have used one of the symbols I learned there: three little dots placed in the shape of a triangle, which stand for the word "therefore"!
I would spend hours working on a problem, and eventually, on a good day, I would be able to write the conclusion: because of thus and so, "therefore" such and such is true. I loved getting an answer — and sometimes I was even right! I don't do fancy math anymore, but every time I see the word "therefore" in Scripture, I mark it with those same three little dots. Then I study to see what the "therefore" is there for.
Paul had a problem to solve, and this is his conclusion: God's grace + Paul's weakness = Christ's power: "therefore" when Paul is weak, Christ is strong.
Tired, worn out, and weak-kneed? In financial distress? Struggling with family issues? Then we are in the very best place — Christ's strength.
Prayer: Lord, help us to remember and rejoice in the fact that Your grace + our weakness = Christ's power at work in us! In Jesus' name, we pray. Amen.
