1 Peter 1:10-12 - Concerning this salvation, the prophets, who spoke of the grace that was to come to you, searched intently and with the greatest care, trying to find out the time and circumstances to which the Spirit of Christ in them was pointing when He predicted the sufferings of Christ and the glories that would follow. It was revealed to them that they were not serving themselves but you, when they spoke of the things that have now been told you by those who have preached the gospel to you by the Holy Spirit sent from heaven. Even angels long to look into these things.
One of the basic principles and safeguards for the interpretation of any Scripture is to "always proceed from then to now." Determining what a text of Scripture meant in its original setting and context is known as the historical-grammatical method of interpreting Scripture. Using this approach preserves us from eisegesis (reading into Scripture) when we make our applications for today. So, as a rule of thumb, we should never make present-day applications of Scripture before we have determined, as best we can, what was meant when the Scripture was written.
