Sons of God

"He came unto his own, and his own received him not. But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: " (John 1:11-12).

How do you know that Jesus is the Son of God? Still a challenging question today.
How did Jesus prove to be the Son of God? for without proofs, it's blasphemous to make such a claim. "The Jews answered him, We have a law, and by our law he ought to die, because he made himself the Son of God." (John 19:7). The Jews are saying to Jesus,"if you are truly what you claim to be,you must prove it". Jesus didn't take any offense but said in John 10:36-38;
"Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God? If I do not the works of my Father, believe me not. But if I do, though ye believe not me, believe the works: that ye may know, and believe, that the Father is in me, and I in him".
So didn't Jesus prove Himself to the Jews? Of course He did through is Words and mostly through signs - miracles and wonders, that is, the works of the Father.
To claim you represent a kingdom, you must present infallible proofs. This did Jesus so very often: turning water into wine at a wedding, being His first given public sign (John 2:1-11). He raised the dead; He gave sight to the blind; He healed the sick, He cast out devils,etc. [Read John 9,11]..."And many other signs truly did Jesus in the presence of his disciples, which are not written in this book: But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name." (John 20:30-31).
[Note:  Signs are supposed to be as numerous as the "stars of heaven". Signs should be seen everywhere because believers are everywhere, even thou the deceiver (i.e, the devil) will fake many of these signs through his ministers (2 Cor 11:14)].

So now we see that without living (infallible) proofs, many will not believe that Jesus is the Son of God. This is the primary reason we are being given POWER! to become like Jesus! He gave us Power! to be His witnesses!"...But as many as received him, to them gave he power to become the sons of God,..". [Note: The Church received this power on the day of Pentecost in Acts 2].
This power is given to be His witnesses here on earth - to speak, declare and command with understanding  [I N] the authourity of  His name, for signs to follow. When we speak with the understanding of who we are in Christ, the bible says in John 5:25  "Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live."  It simply says that when we witness in His name, the dead ( i.e, the unbelievers and physically dead bodies) shall definitely "be touched" and saved by Him. We must have faith in what we say about Jesus Christ to others,for we are in the hour where whatsoever you say and declare in the name of Jesus Christ counts so very,very much.
Learn daily at His feet and be bold to declare His worth to the world! They are the ones He died for (John 3:16). . , Don't be idle.
