Nehemiah 1: 3-4 And they said to me, “The survivors who are left from the captivity in the province are there in great distress and reproach. The wall of Jerusalem is also broken down, and its gates are burned with fire.” 4 So it was, when I heard these words, that I sat down and wept, and mourned for many days; I was fasting and praying before the God of heaven.
Nehemiah 2:1-2 And it came to pass in the month of Nisan, in the twentieth year of King Artaxerxes, when wine was before him, that I took the wine and gave it to the king. Now I had never been sad in his presence before. 2 Therefore the king said to me, “Why is your face sad, since you are not sick? This is nothing but sorrow of heart.”
We should not confuse the anguish that we endure because of the burden that is placed in our heart, to the joy that we received in Him. When Nehemiah was burdened in his heart about the wall of Jerusalem, he looked sad and the king noticed that he was not joyful like before. When someone looks sad, we can not say that they lost the joy of their salvation. It could be because God has placed a burden in their heart like putting an embryo in the womb. As it grows inside the womb the anguish of the mother is too great.
Likewise the anguish of the heart grows more rapid towards God given task or burden. When the child is born all the pain that she went through is gone because a new man or woman born in this world and joy surrounds her. Likewise, when the burden of the Lord is accomplished by His grace and power then the joy we receive because of a new soul is added to God’s family or if one delivered from the bondage of Satan is more than before. This is how we grow in the Lord spiritually by obeying to the burden of the Lord that He places in our heart. The joy will be kept on increasing and it will be full in Christ.
