Our walk begins with being "born again (John 3:7)." We know that we depend upon the Creator for our very life. "The Lord God...breathed into his nostrils the breath of life; and man became a living soul (Genesis 2:7)." But He breathes again upon a man if that person will "believe on his name (John 1:12)." This is how we receive our "new creature (2 Corinthians 5:17)" life.
When Jesus appeared to His disciples the first time after His resurrection, "he breathed on them, and saith unto them, Receive ye the Holy Ghost (John 20:22)." The word breath in Greek is pneuma and means "spirit" or "wind." It is this Holy Spirit which is breathed into our being. In the Bible there are only two times (which represent the two kinds of life) that God breathed upon man in this way.
