'Gladly' in the Bible

When we arrived in Jerusalem, the brothers welcomed us gladly.

For since you are so wise, you put up with fools gladly.

But he said to me, "My grace is enough for you, for my power is made perfect in weakness." So then, I will boast most gladly about my weaknesses, so that the power of Christ may reside in me.

Now I will most gladly spend and be spent for your lives! If I love you more, am I to be loved less?
