When a lost man leaves this world, he finds himself in the midst of the inconceivable judgment of hell (Luke 16:19-31). Yet, when a saved person leaves this world, he finds himself in the glorious presence of the Lord (2 Corinthians 5:8) and in the midst of inconceivable joys (Psalm 16:11). Most Christians have heard about the many mansions in the Father’s house (John 14:2), but the Bible also speaks of the absence of tears, death, sorrow, and pain because “the former things are passed away” (Revelation 21:4). Not only is eternal life going to be great for the believer because of the absence of these things, but even more so because of the presence of the One who died so that believers might have that life.
Man does not change in order to be saved, but true salvation always brings about an evident change in the life of the new believer. Perhaps the change is less noticeable in some new believers and more noticeable in others; however, no change means no salvation. The change is not always an immediate outward change because it involves a change of the inward nature. A person who trusts Christ for salvation becomes a new creature (Galatians 6:15). It might be best to consider how this could be likened to a dog (Matthew 15:26-27) becoming a sheep (John 10:16). A new man now dwells within the new Christian to help combat and defeat the old sinful nature (Ephesians 4:22-24). Salvation is not merely the turning over of a new leaf; it is a new birth (John 3:3) where one is passed from spiritual death to spiritual life (John 5:24).
Nobody likes to spend time around those who act in a rude or insulting manner. Most people would rather spend people-time with those who focus on saying nice things. However, the truth is that one is just as spiritually dangerous to one's well-being as the other. This is why the Bible warns us to “meddle not with him that flattereth with his lips.” Flattery is directly connected to deceit and covetousness; therefore, God intends for His warning to help Christians avoid people who say nice things deceitfully. These people intend to take advantage of their target. Far too many people have been mistreated and lied to by others whom they thought to be dear friends. It is best to avoid those with flattering lips.
