Just take a moment to take in the fact that the Person of Christ Jesus, God the Father and The Person of the Holy Spirit whom you speak to every time you pray is the same persons who created us and everything around us but also the same person's who helped, talked with Moses and many others and they stand outside of time, whatever that means observing and interacting in the lives of all humanity.
When we pray we are speaking to the Ancient of Days (Danial 7:9), who is The Father of Time ( Genesis 1:1, Colossians 1:16) who is not time, time is in him ( Acts 17:28) and then there is the metaphor of Psalm 90:4, "The Thousand Years".
We have no frame of reference for what time is or what time isn't, like our consciousness we lack the cognitive ability to comprehend it.
Therefore we need to realize that God operates in the cosmos, the world and in our lives based on his frame of reference and not ours. So when we become unhappy or upset over what we deem a lack of response to prayers we show our ignorance of our God and his providence.
So what I would like you to consider NOW, today is that the hourglass of your life is running out. But God had us in mind when he made provisions for "a time for every matter under heaven” (Ecclesiastes 3:1):
a time to be born, and a time to die; a time to plant, and a time to pluck up what is planted; a time to kill, and a time to heal; a time to break down, and a time to build up; a time to weep, and a time to laugh; a time to mourn, and a time to dance. (Ecclesiastes 3:2–4)
Two thousand years after Christ (2 God years!) we should remember: The Lord is not slow to fulfill his promise as some count slowness, but is patient toward [us], not wishing that any should perish, but that all should reach repentance. (2 Peter 3:9)
It comes down to this today and everyday we remain on this earth. God's timing is very different than ours, he is constantly thinking about you and acting on your behalf.
15 My times are in your hand;
rescue me from the hand of my enemies and from my persecutors!
Being confident and relaxed with being in God's hands will humble us to slow down, to be more contemplative and to pray more. This facet of our spiritual maturity will results one day in us being exalted by God in either life of death.
1 Peter 5:6-7
6 Humble yourselves, therefore, under the mighty hand of God so that at the proper time he may exalt you, 7 casting all your anxieties on him, because he cares for you.
