Jesus promises the Holy Spirit

John 14:16-21, 25-27 16 16 And I will ask the Father, and he will give you another advocate to help you and be with you forever— 17 the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you. 18 I will not leave you as orphans; I will come to you. 19 Before long, the world will not see me anymore, but you will see me. Because I live, you also will live. 20 On that day you will realize that I am in my Father, and you are in me, and I am in you. 21 Whoever has my commands and keeps them is the one who loves me. The one who loves me will be loved by my Father, and I too will love them and show myself to them.
25 All this I have spoken while still with you. 26 But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you. 27 Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid.

Here we see the wonderful work of the Trinity God, the Son Lord Jesus, asked the Father to give us the Holy Spirit, the advocate, that he may be with us forever. The Holy Spirit is always with us and will live in us. The Holy Spirit teaches us and reminds us of everything the Lord Jesus said. This is the Spirit of truth, who speaks the truth, while the devil, the king of the world, speaks lies. The Holy Spirt also comforts us, and the Lord Jesus comforted the disciples, saying: Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid. The Lord Jesus also said that there is trouble in the world, but in Him there is peace, and the Lord Jesus also encouraged His disciples: Whoever has my commands and keeps them is the one who loves me. The one who loves me will be loved by my Father, and I too will love them and show myself to them. The Lord will manifest to those who love him, wonders God has prepared in heaven for those who love him.
May God bless you and your family. 🙏😀
