There is no need to rush off into allegations of imbalance. Without question some verses on prayer have been abused by people teaching weird doctrines. This one may even get the prize for “most abused”. Still, if we ever needed a motivation to pray, the following words of Jesus have to rank among the best.
And whatever things you ask in prayer, believing, you will receive.” – Matthew 21:22 (NKJV)
Christ wants us to pray. He says this to encourage us to pray. The main reason behind this encouragement is likely that the Father desires to answer our prayers and Christ knows that better than anyone. He wants what is best for His people and, therefore, He wants us to pray, asking things, believing, so that we will receive.
Central Reflections 
I struggle with this “And whatever things you ask in prayer, believing, you will receive.” – Matthew 21:22 (NKJV)”
Because I wonder what if what I am praying for isn’t what God wants for me. Maybe he has another plan and what I am asking for doesn’t fit in that plan. This then shakes my confidence to believe that what I ask for I will receive. I hope but I can’t say for sure whether it will happen or not.
bev47, You’re not alone in that little struggle – and certainly God’s will takes priority over ours when we pray.
Perhaps the key is in cultivating a greater appreciation for just how much He loves us and how much we are able to trust Him.
Focusing on those two things – His love, our capacity to trust – can help us to more truly desire His will – even when we aren’t 100% sure what it is. We may not get exactly what we want all the time, but that won’t cause our confidence to be shaken or feel like such a struggle. It can be more like cheerful submission to a wise and loving Father who desires our absolute best.
