He proved it when He sent His Son to die for us. And He went to that extreme measure because He wants to have fellowship with us. And because God loves you so much He has many blessings He wants to give you. But you need to be walking with Him, obeying Him, trusting Him, in order for Him to be able to bless you.
So keep yourself in the love of God. Keep yourself in the place where God can do the things for you that He wants to do.
