'Sufficient' in the Bible

Therefore don't be anxious for tomorrow, for tomorrow will be anxious for itself. Each day's own evil is sufficient.

Philip answered him, "Two hundred denarii worth of bread is not sufficient for them, that everyone of them may receive a little."

Sufficient to such a one is this punishment which was inflicted by the many;

to the one a stench from death to death; to the other a sweet aroma from life to life. Who is sufficient for these things?

not that we are sufficient of ourselves, to account anything as from ourselves; but our sufficiency is from God;

who also made us sufficient as servants of a new covenant; not of the letter, but of the Spirit. For the letter kills, but the Spirit gives life.

He has said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me.
