Some things to think about...
Spend your time in nothing which you know must be repented of. In nothing on which you might not pray for the blessing of God. In nothing which you could not review with a quiet conscience on your dying bed. In nothing which you might not safely and properly be found doing if death should surprise you in the act.
God is down in front. He is in the tomorrows. It is tomorrow that fills men with dread. God is there already. All the tomorrows of our life have to pass Him before they can get to us.
F. B. Meyer
I am His by purchase and I am His by conquest; I am His by donation and I am His by election; I am His by covenant and I am His by marriage; I am wholly His; I am peculiarly His; I am universally His; I am eternally His. Once I was a slave but now I am a son; once I was dead but now I am alive; once I was darkness but now I am light in the Lord; once I was a child of wrath, an heir of hell, but now I am an heir of heaven; once I was Satan's bond-servant but now I am God's freeman; once I was under the spirit of bondage but now I am under the Spirit of adoption that seals up to me the remission of my sins, the justification of my person and the salvation of my soul. ... Thomas Brooks
Breezy, self-confident Christians tell us how wonderful it is to accept Christ and then have a good time all the rest of your life; the Lord won't demand anything of you. Yes, He will, my friend! The Lord will demand everything of you. And when you give it all up to Him, He may bless it and hand it back, but on the other hand He may not. . . . A.W. Tozer
