Many have tons of religion, but not an ounce of salvation. Any fool can criticize, condemn, and complain - and most fools do. If Christians do not come apart from the world and rest awhile, they may just plain come apart. No sin is small for it is against an eternal God. Assurance of salvation is not in WHAT you know, but in WHO you know.
Faith steps out when pride steps in.
Don't copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will know what God wants you to do, and you will know how good and pleasing and perfect his will really is.
