Evoke Him, keep meditate daily (because meditating is basic for everything in your Spiritual evolution and life) to develope your senses which will help you to hear Him, be able to communicate with Him with higher effectiveness.
You can use tools in the beginning to communicate with Him if you can’t do it Him yet; for example candle light, incense smoke or pendulum. Putting His sigil under your pillow is also can be an option, you have a chance to see Him in your Dream and contact with Him.
You can also give Him sometimes offerings, and keep talking to Him in your mind, because He’ll hear you, so even if you can not get His messages, He’ll get yours and probably He’ll guide you.
You can spend with Him some quality times later
(which is also a very kind offering to Him or any Deity in basic).
Much bless on you
