Mark 13:3 And as he sat upon the mount of Olives over against the temple, Peter and James and John and Andrew asked him privately,
Mark 13:4 Tell us, when shall these things be? and what shall be the sign when all these things shall be fulfilled?
Jesus answers them in a broader time frame; more as to the end times, the time following his ascension and his return. Jesus shall make a new covenant, a better covenant with them. There would be no need of a temple such as they had to house God and do sacrifices. Jesus is the sacrifice and the way to God.
The Samaritan woman heard of the true way of worship.
John 4:21 Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain, nor yet at Jerusalem, worship the Father.
John 4:22 Ye worship ye know not what: we know what we worship: for salvation is of the Jews.
John 4:23 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
John 4:24 God is a Spirit: and they that worship him must worship him in spirit and in truth.
John 4:25 The woman saith unto him, I know that Messias cometh, which is called Christ: when he is come, he will tell us all things.
John 4:26 Jesus saith unto her, I that speak unto thee am he.
James 4:6 But he giveth more grace. Wherefore he saith, God resisteth the proud, but giveth grace unto the humble.
His disciples were expecting Jesus to return soon.
Mark 13:5 And Jesus answering them began to say, Take heed lest any man deceive you:
Mark 13:6 For many shall come in my name, saying, I am Christ; and shall deceive many.
I am Christ or they teach a false Christ: Love and light from God, but not of Jesus Christ. A Jesus that is not as the Bible describes him, a Jesus of their making. Beware of familiar words, for they often have a different meaning, a different spirit behind them. Love, light, my truth, tolerance, unity even Jesus. Test all words in the context of the Bibles truth. Ask questions, beginning with: who is Jesus? Has he forgiven your sins? These will reveal the spirit behind the talk...familiar words but an unfamiliar spirit. The spirit of antichrist.
1 John 2:18 Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.
1 John 2:19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
1 John 2:22 Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.
1 John 4:3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
1 John 4:4 Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.
1 John 4:5 They are of the world: therefore speak they of the world, and the world heareth them.
1 John 4:6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
