Is Faith alone enough??

For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life - John 3:16

Through this one verse we can understand that God is true! Simply by this verse, like seriously with just this one verse. People are so quick to show this one exact verse but what about the rest of the bible??

Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on them - John 3:36

I have seen these two verses many times in my life of faith, but why is it people still justify their faith with just these two?.. wouldn't that make our faith in God contained to a fortune cookie?

Yes these are the first steps to believing in God.... But our belief in God is for us to reach to the kingdom of Heaven! (1 pt 2:9) I want to know God! I want to feel close to God; I need to know who God is! But God lets us know who they are through the bible.

We know that we have come to know him if we keep his commands - 1 John 2:3

Then not only by belief can we enter the Kingdom of Heaven we must keep Gods commands... Then were are God's Commands written and set? What are God's Commands exactly???
