1 John 5:3-4 (HCSB)

For this is what love for God is:to keep His commands. Now His commands are not a burden, because whatever has been born of God conquers the world. This is the victory that has conquered the world:our faith.

     John packs a lot of truth into these verses.
  1. Love for God means keeping his commandments – It is no good to claim that we love God and then disobey him.  We live a lie when we do that.  Do we keep God’s commandments? Then we love him.  Do we not keep his commandments? Then we do not love him.
  2. God’s commands are not a burden. The word “burden” means “heavy or hard.” God is not asking us to do the impossible.
  3. Whatever—or as we think of it, whoever—has been born of God and keeps his commandments, overcomes the world.
  4. The specific mechanism with which we overcome the world? Our faith.  This then is the importance of and reason for faith.  By it, we overcome the world.
Calvin:  This passage is remarkable for though Satan continually repeats his dreadful and horrible onsets, yet the Spirit of God, declaring that we are beyond the reach of danger, removes fear, and animates us to fight with courage… It is, indeed, true, that our warfare continues through life, that our conflicts are daily, nay, that new and various battles are every moment on every side stirred up against us by the enemy; but as God does not arm us only for one day, and as faith is not that of one day, but is the perpetual work of the Holy Spirit, we are already partakers of victory, as though we had already conquered.
