1 John 4:4

2 Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God.
3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.

These things have I written unto you concerning them that seduce you.

And my temptation which was in my flesh ye despised not, nor rejected; but received me as an angel of God, even as Christ Jesus.

For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.

Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
