'Effective' in the Bible

“Are the consolations of God [as we have interpreted them to you] too trivial for you,[Or] were we too gentle toward you [in our first speech] to be effective?

but He has said to me, “My grace is sufficient for you [My lovingkindness and My mercy are more than enough—always available—regardless of the situation]; for [My] power is being perfected [and is completed and shows itself most effectively] in [your] weakness.” Therefore, I will all the more gladly boast in my weaknesses, so that the power of Christ [may completely enfold me and] may dwell in me.

For the word of God is living and active and full of power [making it operative, energizing, and effective]. It is sharper than any two-edged sword, penetrating as far as the division of the soul and spirit [the completeness of a person], and of both joints and marrow [the deepest parts of our nature], exposing and judging the very thoughts and intentions of the heart.
