Regarding the account in Genesis 28 of Jacob and the ladder or staircase reaching from earth into heaven and the angels of God were ascending and descending on it. Why would they be doing this? I believe that it is in response to what we are calling for. Because they are ministering spirits sent out in the service of Christians, their job is to is to go into the invisible realm, the realm of heaven and bring back what you are calling and believing for based on God’s word.
Voice activation is where you use your own words to activate things and this is not something new. In April 2011 Apple launches Siri, the first digital assistant and we were all wowed by the technology where you can say things and the technology responded. Hay Siri! What's the weather forecast today? Hay Siri! Turn the volume up. We can get so amazed by technology especially the things that make our lives easier, that it tends takes away from the method or systems put in place by God. From the dawn of creation, God chose voice activation as a way to create things and He Himself uses the same method and calls things that do not exist as though they did. I want to show you this scripture in Rom 4 regarding God’s method of voice activation. Romans 4:17  (NKJV) 17 (as it is written, “I have made you a father of many nations”) in the presence of Him whom he believed—God, who gives life to the dead and calls those things which do not exist as though they did;
For we walk by faith, not by sight. - In these eight words the apostle Paul is giving us great insight how to operate in faith and he is saying to be successful in the kingdom of God, because you have to walk by faith and not by what you see in the natural. We all have the power of God, the Holy Spirit abiding on the inside of us, ever present to empower the things that we say in faith, but the pressures of the natural realm are continually working against your faith and your confession. 
Believing is a choice and we have to become like children in regards to believing because children will believe whatever their parents tell them and that’s why it is so important what we tell our kids. My favorite thing to do with my children was before they went to sleep was to tell them a bible story about men and women of faith. Believing is not hard, it is just a choice.
The anointing of the Holy Spirit has amazing qualities which is well beyond natural things or abilities. The anointing that you receive from Him abides in you and that same anointing teaches you concerning all things. So, when you realise this, you can begin to exercise your faith and ask the Holy Spirit to teach and instruct you regarding the issue or yoke that is hindering you.
Jesus wants you to have a story, to have a testimony of what He has done for you. One of the keys to moving in the Holy Spirit is telling someone, “Let me tell you what happened to me, let me tell you my story”. Ask them, “have you ever been healed?” People want to know someone they know who was healed. To receive a miracle, we have to get the seed of faith into our heart. So how do we do this? We do with our words.
