When we study the subject of the soul, we must answer the following three questions: First, where does our soul come from? Second, why does our soul put on flesh and live in this sinful world? And third, where does our soul go after we die? These three questions are very important for the hope of all mankind.
Let's look carefully at the words of Jesus who gives definite answers to all these questions and the profound truths of the Creator spoken through the prophets, passed on over thousands of years.
Apostle Paul wrote:

Heb.11:15~16 If they had been thinking of the country they had left, they would have had opportunity to return.

This verse means that if anyone does not think of the county he left, he has no opportunity to return. Certainly there is a place where the human soul comes from and where it goes. The body is born and perishes in this world, but the soul returns to wherever it came from. So the forefathers of faith admitted that they were aliens and strangers on earth. When Jacob, the forefather of Israel, was asked how old he was, he replied to Pharaoh, king of Egypt, as follows:

Gen. 47:8~9 Pharaoh asked him, "How old are you?" And Jacob said to Pharaoh, "The years of my pilgrimage are a hundred and thirty.

Heb. 11:13~16 And they admitted that they were aliens and strangers on earth. People who say such things show that they are looking for a country of their own.

All the above words spoken by the forefathers of faith tell us that all men in this world are aliens and strangers who have come from heaven, their previous world. Nevertheless, there are not many who think of their own country. It's because they completely lost their memory of the previous life by putting on a veil of sin. The prophet Isiah wrote in regard to this matter as follows:

Isa. 59:2 But your iniquities have separated you from your God; your sins have hidden his face from you, so that he will not hear.

In the spiritual world, we were noble angels, or the sons of God. However, because of our sins we have come to this world; our spiritual eyes are covered with the veil of sin, so that we cannot see the things of the heavenly country. But sometimes we are unwittingly reminded of our previous life in heaven. It's because our soul, given by God, occasionally transcends the veil of our sinful flesh and looks at the heavenly country.

Thanks to God the Father and God the Mother forgiving our sins, we can return to our heavenly home.
