"Yet the number of the children of Israel shall be as the sand of the sea, which cannot be measured nor numbered; and it shall come to pass, that in the place where it was said unto them, Ye are not my people, there it shall be said unto them, Ye are the sons of the living God." (Hosea 1: 10)
This prophecy is for us today, not just because we are now sons of the Living God.
Just as important, He is a living God.
He is alive!
David did not face off with Goliath, trusting in a figment of his imagination:
"And David spake to the men that stood by him, saying, What shall be done to the man that killeth this Philistine, and taketh away the reproach from Israel? for who is this uncircumcised Philistine, that he should defy the armies of the living God?" (1 Samuel 17: 26)
"Then said David to the Philistine, Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of the LORD of hosts, the God of the armies of Israel, whom thou hast defied." (1 Samuel 17: 45)
God is alive, and alive to us because of Jesus:
"Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood," (Revelation 1: 5)
He lives in us:
"20I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. 21I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain." (Galatians 2: 20-21)
He is our life:
"3For ye are dead, and your life is hid with Christ in God. 4When Christ, who is our life, shall appear, then shall ye also appear with him in glory." (Colossians 3: 3-4)
He is working within you to do what He wants you to do:
"12Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. 13For it is God which worketh in you both to will and to do of his good pleasure." (Philippians 2: 12-13)
Today, He is not sitting far away, uninterested or unconcerned about the problems we face. He lives to intercede on your behalf:
"Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them." (Hebrews 7: 25)
"Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us." (Romans 8: 34)
