‘Do not fear [anything], for I am with you;
Do not be afraid, for I am your God.

I have told you these things, so that in Me you may have [perfect] peace. In the world you have tribulation and distress and suffering, but be courageous [be confident, be undaunted, be filled with joy]; I have overcome the world.” [My conquest is accomplished, My victory abiding.]

And Jesus answered, “You unbelieving and perverted generation, how long shall I be with you? How long shall I put up with you? Bring him here to Me.” Jesus rebuked the demon, and it came out of him, and the boy was healed at once. Then the disciples came to Jesus privately and asked, “Why could we not drive it out?” He answered, “Because of your little faith [your lack of trust and confidence in the power of God]; for I assure you and most solemnly say to you, if you have [living] faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and [if it is God’s will] it will move; and nothing will be impossible for you.

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.

In his illness, You will restore him to health.

Now I, Nebuchadnezzar, praise and exalt and honor the King of heaven, for all His works are true and faithful and His ways are just, and He is able to humiliate and humble those who walk in [self-centered, self-righteous] pride.”

I am numb and greatly bruised [deadly cold and completely worn out];
I groan because of the disquiet and moaning of my heart.

“Woe to me because of my [spiritual] brokenness!” [says Jeremiah, speaking for the nation.]
