The reason I love God: because He loves me, because He does forgive me of my sin through the sacrifice of his Son, he gave up his Son to a death on a cross for me, why shouldn't I love him. God brings peace to my life when troubles seem to rule the day. He allows me to live another day, this is one of many reasons to love him and to worship him. He has given me eternal life. He gives me opportunities to help others when they have needs I can help with. He gives me good loving friends who care for me even with all my faults. He's my Father, friend, companion, savior, prayer partner, provider and no one else comes close to fulfilling my life as he does, there is so much more but I believe you can see why I love God.
God loves those who believe and those who do not and the same goes for me, you have no choice in this matter. That puts the matter of total free will to rest.
