First John 5:14–15 says, "And this is the confidence that we have toward him, that if we ask anything according to his will he hears us. And if we know that he hears us in whatever we ask, we know that we have the requests that we have asked of him." How can we know if we're praying in accordance with God's will? The Bible is full of instruction and example.
How do I know if I'm praying in line with the will of God?
First Thessalonians 5:16–18 says, "Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you." So, we know praying and giving thanks are God's will.
To follow God's will in prayer, we need wisdom—that is, instruction and guidance from Him. This, remarkably, is available. James 1:5–6 says, "If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him. But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind."

We can pray trusting that God is for His children. We may not always know what His specific will is, but we can rely on Him to do what is right and best. So we pray in submission to Him, asking for His will to be done (Matthew 6:10). "And we know that for those who love God all things work together for good, for those who are called according to his purpose" (Romans 8:28).
