God is a rewarder of those who diligently seek Him. Diligence begins by keeping our heart in the love of God. Never settle for the nominal Christian life that is nothing more than going to a church building and occasional times of reading Scripture and worship. There is no reward in that kind of faith.
To walk in diligence before Jesus means that we will love Him supremely, walk in all of His ways, keep His commandments, and serve Him with all of our heart and soul. After receiving Jesus Christ as Messiah/Savior, we are to diligently add to our faith successively and progressively virtue, knowledge, self-control, perseverance, godliness, brotherly kindness, and love.
This diligence makes one’s fellowship with Jesus Christ rich. This diligence makes one’s faith precious. Peter, when speaking about our looking for the new heavens and new earth, exhorts us to be diligent in the pursuit of peace, and ìwithout spot and blameless. After all, God has been and is continually extremely diligent on our behalf.
