James 2:26 New King James Version (NKJV)
26 For as the body without the spirit is dead, so faith without works is dead also.
The word used for spirit in this passage is "pneuma" which is also translated as "breath".
When God places the spirit into an unborn child it has received the "breath of life".
God told Jeremiah "I knew you in the womb". "You" is the spirit. The real "you" is a spirit who lives in an earth suit.Jeremiah 1:4-6 New King James Version (NKJV)
The Prophet Is Called
4 Then the word of the Lord came to me, saying:
5
“Before I formed you in the womb I knew you;
Before you were born I sanctified you;
I ordained you a prophet to the nations.”
Therefore, you are alive in the womb before you breathe any oxygen.
