Romans 8:14-16
14 For all who are led by the Spirit of God are sons of God.
15 For {the Spirit which} you have now received {is} not a spirit of slavery to put you once more in bondage to fear, but you have received the Spirit of adoption {the Spirit producing sonship} in {the bliss of} which we cry, Abba (Father)! Father!
16 The Spirit Himself {thus} testifies together with our own spirit, {assuring us} that we are children of God.
John 16:13-15
13 But when He, the Spirit of Truth (the Truth-giving Spirit) comes, He will guide you into all the Truth (the whole, full Truth). For He will not speak His own message {on His own authority}; but He will tell whatever He hears {from the Father; He will give the message that has been given to Him}, and He will announce and declare to you the things that are to come {that will happen in the future}.
14 He will honor and glorify Me, because He will take of (receive, draw upon) what is Mine and will reveal (declare, disclose, transmit) it to you.
15 Everything that the Father has is Mine. That is what I meant when I said that He {the Spirit} will take the things that are Mine and will reveal (declare, disclose, transmit) it to you.
Joshua 1:8
This Book of the Law shall not depart out of your mouth, but you shall meditate on it day and night, that you may observe and do according to all that is written in it. For then you shall make your way prosperous, and then you shall deal wisely and have good success.
