Everything we do is either for God or against God. There is no middle ground. The thing we do either builds faith or chokes it. Even though there is nothing “wrong” with some computer games, TV, movie, music or other entertainment – the thing we do either builds faith in us or it chokes the word of God:
If we are not with Jesus, we are actually against him:
Matthew 12:30 King James Version (KJV)
30 He that is not with me is against me; and he that gathereth not with me scattereth abroad.
If we love the things of the world (movies, TV, entertainment, shopping, sports etc), the love of the Father is not in us:
1 John 2:15-17King James Version (KJV)
15 Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.
16 For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
17 And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.
The things of the world chokes the word so that it becomes useless:
Mark 4:19 King James Version (KJV)
19 And the cares of this world, and the deceitfulness of riches, and the lusts of other things entering in, choke the word, and it becometh unfruitful.
Faith comes from hearing the word of God:
Romans 10:17 King James Version (KJV)
17 So then faith cometh by hearing, and hearing by the word of God.
