God brings light

God is the light to all mankind

God gives light to the soul through the Holy Spirit

He brings salvation through the Gospel

God gives light to us through the Word, by the Holy Spirit

He brings understanding and truth via Scripture 

1. He teaches us, illuminates and reveals to the redeemed the deeper spiritual things of Scripture. 

2. He also hides them in our heart and mind, & brings them to our rememberance when we walk daily in Christ and encounter this or that, when we share the gospel, when we have Bible discussions, and sometimes specifically pulls out and reveals things that we might not have realized or put together before (1+1=2).
