Atheists and non-believers always want "context" for every verse. However, the true believer knows that the Bible is the true word of God.
Therefore, we hang on to every word in the Bible.
Jesus said I am the way, the truth, and the life. No one comes to the Father except through me.
John 14:6
The Atheist looks at this verse and demands more context to prove it is true. The true believer already knows it's true and will quote it to other believers as both a gift and a reminder of who Jesus is.
This may sound harsh, but the Bible was not written to prove God's existence. Nor was it written for Atheists and non-believers.
If you are struggling with the need for "context" for every verse, I would urge you, my friend, to examine your heart and ask why it is so. Everyone—including the most prominent pastors, elders, and teachers—has, at one time or another, struggled with unbelief concerning the Bible. Maybe you are going through that right now, to some degree.
