He is the Supreme Being

Worthy are You, our Lord and God, to receive glory and honor and power, for You created all things, and by Your will they existed and were created. (Revelation 4:11 ESV)

 In our inner lives we can be deeply aware of God and all that He is and has done. We can remember His attributes, His power, and His love.
We can realize that God has told us about Himself through His Word—that He’s Father, Son, and Holy Spirit. He’s told us what He’s like, what He’s done, how to be reconciled with Him, how to receive Him, how to have His Spirit dwell in us.
 Through His Word He’s shown us how to know and love Him, how to trust Him, what pleases Him. He’s expressed His love, His faithfulness, His care for us. We can therefore know Him, love Him, rely on Him, and confidently believe in, trust, and obey His Word.
 In our inner lives, in our spirits, we can glorify God by always remembering that He is God, and what that means.—That He is the Supreme Being who has made us, who knows everything about us and everything else; and who, as majestic as He is, loves us and wants to have a personal relationship with us
 We are to love God, and thus glorify Him, from within our inward being, with our soul/spirit, with our rational minds, and with all that is within us. —Peter Amsterdam [1]

 We must love God with all our hearts, must look upon Him as the best of beings, in Himself most amiable, and infinitely perfect and excellent; as One whom we lie under the greatest obligations to, both in gratitude and interest. —Matthew Henry
