When we say “AMEN” after we pray are we hanging up on God?
Jesus seldom said “AMEN”.
John 16:33 AMP
I have told you these things, so that in Me you may have [perfect] peace. In the world you have tribulation and distress and suffering, but be courageous [be confident, be undaunted, be filled with joy]; I have overcome the world.” [My conquest is accomplished, My victory abiding.]
John 17:1-26 AMP
When Jesus had spoken these things, He raised His eyes to heaven [in prayer] and said, “Father, the hour has come. Glorify Your Son, so that Your Son may glorify You.  Just as You have given Him power and authority over all mankind, [now glorify Him] so that He may give eternal life to all whom You have given Him [to be His—permanently and forever].  Now this is eternal life: that they may know You, the only true [supreme and sovereign] God, and [in the same manner know] Jesus [as the] Christ whom You have sent.  I have glorified You [down here] on the earth by completing the work that You gave Me to do.  Now, Father, glorify Me together with Yourself, with the glory and majesty that I had with You before the world existed.  “I have manifested Your name [and revealed Your very self, Your real self] to the people whom You have given Me out of the world; they were Yours and You gave them to Me, and they have kept and obeyed Your word.  Now [at last] they know [with confident assurance] that all You have given Me is from You [it is really and truly Yours].  For the words which You gave Me I have given them; and they received and accepted them and truly understood [with confident assurance] that I came from You [from Your presence], and they believed [without any doubt] that You sent Me.  I pray for them; I do not pray for the world, but for those You have given Me, because they belong to You;  and all things that are Mine are Yours, and [all things that are] Yours are Mine; and I am glorified in them.  I am no longer in the world; yet they are still in the world, and I am coming to You. Holy Father, keep them in Your name, the name which You have given Me, so that they may be one just as We are.  While I was with them, I was keeping them in Your name which You have given Me; and I guarded them and protected them, and not one of them was lost except the son of destruction, so that the Scripture would be fulfilled.  But now I am coming to You; and I say these things [while I am still] in the world so that they may experience My joy made full and complete and perfect within them [filling their hearts with My delight].  I have given to them Your word [the message You gave Me]; and the world has hated them because they are not of the world and do not belong to the world, just as I am not of the world and do not belong to it.  I do not ask You to take them out of the world, but that You keep them and protect them from the evil one.  They are not of the world, just as I am not of the world.  Sanctify them in the truth [set them apart for Your purposes, make them holy]; Your word is truth.  Just as You commissioned and sent Me into the world, I also have commissioned and sent them (believers) into the world.  For their sake I sanctify Myself [to do Your will], so that they also may be sanctified [set apart, dedicated, made holy] in [Your] truth.  “I do not pray for these alone [it is not for their sake only that I make this request], but also for [all] those who [will ever] believe and trust in Me through their message,  that they all may be one; just as You, Father, are in Me and I in You, that they also may be one in Us, so that the world may believe [without any doubt] that You sent Me.  I have given to them the glory and honor which You have given Me, that they may be one, just as We are one;  I in them and You in Me, that they may be perfected and completed into one, so that the world may know [without any doubt] that You sent Me, and [that You] have loved them, just as You have loved Me.  Father, I desire that they also, whom You have given to Me [as Your gift to Me], may be with Me where I am, so that they may see My glory which You have given Me, because You loved Me before the foundation of the world.  “O just and righteous Father, although the world has not known You and has never acknowledged You [and the revelation of Your mercy], yet I have always known You; and these [believers] know [without any doubt] that You sent Me;  and I have made Your name known to them, and will continue to make it known, so that the love with which You have loved Me may be in them [overwhelming their heart], and I [may be] in them.”
John 18:1 AMP
Having said these things, Jesus left with His disciples and went across the ravine of the Kidron. There was a garden there, which He and His disciples entered.
