Are you into reading? This book that I'm reading, "Knowing God" by J.I. Packer would give you the right perspectives about knowing God's characters. I know it deeply affects me and I would never "look" at God the same way again. I'm just simply overwhelmed by Him, His characters and His love for me.
Secondly, it's a natural sin in every human's being to not wanting a natural relationship/devotion with God. Why? because we're just sinful creatures. We just want it everything to be easy and instant. It takes lots of work and commitment on your part to nourish your relationship with God just like any other relationships. (I won't know my boyfriend or friend's characters if I don't spend enough time with her, correct?) Yet at the same time, God will give you much grace and blessings along the way.
Don't believe of the lies that God doesn't listen or never did anything to you. Consider this: initially, we are just sinners that deserve God's wrath and hell. We don't deserve anything to start with...not even a grace, not even a blessing in our lifes. But God, in His excellent goodness, sent His ONE and ONLY son to suffer and die for you and me for free by grace! If God gave His one and only son for us, what else could he not give us?
It's great that you are obeying Him and follow His ways, but we do all these not to gain God's favors. Yet, there is a blessing for doing that. Try Deutronomy 11, see how God has promised and blessed Israel in that time if they follow and obey His laws. God is an unchanging God - He can and will do those things happened thousand years ago to us today. Yes, today! He is the same yesterday, today and tomorrow.
If you say you believe the Bible and everything in it.. keep reading it. You said you don't even know if he listens to your prayers?... well keep reading your bible, because those are God's only words to you and I found many evidences in the bible that explains that God know my every tears and listens to every prayers and He loves me.
Jeremiah 29:11: For I know the plans I have for you," declares the LORD, "plans to prosper you and not to harm you, plans to give you hope and a future. Then you will call upon me and come and pray to me, and I will listen to you. You will seek me and find me when you seek me with all your heart. I will be found by you," declares the LORD.
Hope I don't offend you in any way but I just wanted to honestly share what the Lord has been showing to me in my Christian life these past few years. Be blessed and I pray that your daily communion with the Lord would be of joy and sweetness.
