Mark 1:15 (KJV) And saying, the time is fulfilled, and the kingdom of God is at hand: repent ye, and If Holy Spirit indwells in us, we will be Witnesses to Jesus
Let us examine Gospel Words of Jesus and New Testament books verses carefully to understand the truth.
1) Jesus said once we receive the Holy Spirit (Power) we (Disciples) will be His witnesses and not to Old Testament God or to any God in any other names.
Acts 1:8 (KJV) But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
2) The Holy Spirit is given only when one obeys Jesus Words.
John 14:15-17 (KJV) If ye love me, keep my commandments.
And I will pray the Father, and he shall give you another Comforter, that he may abide with you forever; Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
Only on obeying Jesus Words Disciples and Apostles were given Holy Spirit.
Acts 5:32 (KJV) And we are his witnesses of these things; and so is also the Holy Ghost, whom God hath given to them that obey him.
Let us ask and answer below questions to see and examine above learnt truth in this real-life world
How can it be possible to go to building churches and listen to other than Gospel sermons and be called Christians without faithful surrendering life to follow Jesus Words?
Without surrendering to Jesus Words Holy Spirit will never be indwelling in one's life. How come fallen from pastors and preachers without being Jesus' witness be calling themselves serving God?
How can one be obeying Jesus by reading and following other not applicable Old Testament verses and calling obedient to Jesus?
Only those doing Jesus Words we will be called Disciples and Christians.
John 8 John 14 and 15 chapters and Acts 11:26
3) Only Jesus Witnesses will be saved in tribulation period before His coming.
Revelation 3:10 (KJV) Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
Conclusion: We understood only way is to be followers of Jesus by doing His Words as disciples and then only Holy Spirit indwells. When Holy Spirit indwells is us, we will be Jesus Witnesses forever. Amen.
