Most Christians do not realize how important our physical bodies are.  The majority of God’s children believe in a bodily resurrection because they have heard it preached so often, but they fail to realize that the bodies that we now have, will be what is resurrected on the last day.  Of course, there are a few, like Jehovah’s Witnesses, for example, who deny that the bodies that we now have will be raised.  They believe in a recreation, not a resurrection.  Paul, however, clearly teaches that it is our present bodies that will be transformed.

Philippians 3:20-21 (NKJV)
²⁰  For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ, ²¹  who will transform our lowly body that it may be conformed to His glorious body, according to the working by which He is able even to subdue all things to Himself.

Our present bodies will be changed, for flesh and blood cannot inherit the kingdom of God (1 Corinthians 15:50), but they will be the same bodies.

1 Corinthians 15:51-53 (NKJV)
⁵¹  Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed– ⁵²  in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed. ⁵³  For this corruptible must put on incorruption, and this mortal must put on immortality.

The same thing that is corruptible now will become incorruptible, and the thing that is now mortal will become immortal.  It is precisely because God has plans for our current bodies that Paul exhorts us to guard them closely, using them as instruments for God’s glory.

Romans 6:12-13 (NKJV)
¹²  Therefore do not let sin reign in your mortal body, that you should obey it in its lusts. ¹³  And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God.

The road that leads to a victorious home in heaven is traveled by those who use their bodies well, refraining from engaging in the common sins of the flesh.  We live in a sex-crazed society, to the point where sex is thought of as a common, ordinary activity.  Marriage is not important to many.  Age is hardly a consideration.  Sex is as common today as eating a peanut butter and jelly sandwich.  It is nothing new.  Paul described the sinfulness of such to the saints at Corinth.

1 Corinthians 6:18-20 (NKJV)
¹⁸  Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body. ¹⁹  Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? ²⁰  For you were bought at a price; therefore glorify God in your body and in your spirit, which are God’s.   

Victory in Christ comes only to those who guard their bodies well, using them as instruments of righteousness rather than unrighteousness.

As you wind down for the night, think about these things.
