“For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.”
Galatians 4:27

Read the main verse, what an interesting instruction. He tells the barren woman to rejoice- to shout! She was still called barren, yet at that state she is expected to rejoice with a shout and also understand that a miracle would be wrought.
The Bible tells us faith gives us an understanding that everything visible was created by that which could not be seen:
“Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.” Hebrews 11:3
Which is the word of God, so when the word tells you:
“My brethren, count it all joy when ye fall into divers temptations;” James 1:2
He is telling you to understand that by faith, there would be solution created that will bring to nothing the diverse trials and temptations.
“…that ye may be perfect and entire, WANTING NOTHING.” James 1:4
