The Apostle Paul wrote in 2 Corinthians 1:20 "For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory."

So much of receiving what God wants to give is about positioning your life to receive it. When it came to receiving the Holy Spirit, the church had to position itself accordingly by being in prayer and fasting for 10 days. God says "Yes" but it is required of us to live out the "amen."
