I pray also that the eyes of your heart may be enlightened in order that you may know (1) the hope to which He has called you, (2) the riches of His glorious inheritance in the saints, and (3) His incomparably great power for us who believe. That power is like the working of His mighty strength, which He exerted in Christ when He raised Him from the dead and seated Him at His right hand in the heavenly realms, far above all rule and authority, power and dominion and every title that can be given, not only in the present age but also in the one to come (Ephesians 1:18-21).

Even When I am old and gray, do not forsake me, O God, until I declare Your power to the next generation, Your might to all who are to come (Psalm 71:18).
The reality of the presence of God is what children need to know for God to be real to them.
We do not wrestle against flesh and blood, but against principalities, against powers, against rulers of the darkness of this age. Against spiritual hosts of wickedness in the heavenly places (Ephesians 6:12).
When Jesus had called the twelve together, He gave them power and authority to drive out all demons, and to cure diseases (Luke 9:1).
Jesus came to them and said: “all authority in heaven and on earth has been given to Me.” (Matthew 28:18).
He was crucified in weakness, yet He lives by God’s power. Likewise we are weak in Him, yet by God’s power we will live with Him to serve… (2 Corinthians 13:4)
But you shall receive power when the Holy Spirit comes upon you (Acts 1:8).
The Kingdom of God is not in word but in power (1 Corinthians 4:20).
I tell you the truth. Anyone who has faith in Me will do what I have been doing. He will do even greater things than these because I am going to the Father. And I will do whatever you ask in My name, so that the Son may bring glory to the Father. You may ask Me for anything in My name and I will do it! (John 14:12-14)
I have given you authority to trample on snakes and scorpions and to overcome all the power of the enemy. Nothing will harm you. However, do not rejoice that the spirits submit to you, but rejoice that your names are written in heaven [and you get to avoid the judgment coming to the world] (Luke 10:17-18).
And these signs will accompany those who believe: in My name they will drive out demons, they will speak in new tongues, they will pick up snakes with their hands, and when they drink deadly poison it will not hurt them at all. They will place their hands on sick people and they will get well (Mark 16:17-18).
If you remain in Me and My words remain in you, ask whatever you will, and it will be done for you. This is to My Father’s glory: that you bear much fruit (John 15:7-8).
Each one should be fully convinced in his own mind (Romans 14:5)
Now to Him who is able to do immeasurably more than all we ask or [can even] imagine – according to His power that is at work within us – to Him be glory in the church and in Christ Jesus throughout all generations (Ephesians 3:20-21).
