By grace God sent his word in the person of Jesus Christ to earth so that by hearing him we may receive faith. However, a man/woman can neither receive faith nor receive the full benefits of the power of faith unless he or she becomes a child of God.
Becoming a child of God means to be three persons in one: the body, the soul and the Holy Spirit, as God is three persons in one: the Father, the Son and the Holy Spirit. It is being three persons in one, and sharing the same spirit with God that confirms you as a child of God. (Romans 8:14:16).
To receive the Holy Spirit, a prerequisite for receiving faith, we should please God by accepting his will as given in the gospel. If we can gladly accept instructions to set up our computer software, how much more should we be glad to accept God's will for our happiness on earth and eternal life hereafter?
In Matthew 3:17 we hear God expressing his love for Jesus: "This is my son whom I love; with him I am well pleased."
Likewise to become children of God and be empowered to receive faith, we should please God by accepting his commandments of which there is a summary in Matthew 22:37-39:
"Thou shall love the Lord thy God with all thy heart and with all thy soul, and with all thy mind. This is the first and the greatest commandment, and the second is like unto it. Thou shall love thy neighbor as thyself."
By loving God, we receive the entire benefit of that relationship because God has no needs for which he requires mortal beings to satisfy. He is completely sufficient within himself. He needs nothing outside himself to complete his happiness or well-being.
By loving God, we bring into our defense arsenal a power second to none in the fight against the evil principalities of this world. This we read in Ephesians 6:10-17.
By loving God we bring love into our hearts, joy to our souls, peace to our minds and goodwill to our neighbors. For God loved us first. He loved us long before we were born, and he showed how much by sending his son to live among us to help us find the path to faith, hope and happiness.
