“See then that ye walk circumspectly, not as fools, but as wise, redeeming the time, because the days are evil” Ephesians 5:15-16.
Being naive is a dangerous character trait. You should expect this world to always be friendly to you. Why not? Because it is dominated by evil! Sin is not human friendly. It is fighting against your soul. Try to live righteously without compromise and you will see it for yourself. The devil will arise against you. He hates you. Well, the good news is that God loves you. So, you have to be wise and submit yourself to God and resist the devil. You need to be careful how you spend your time. If you waste it, you give place to the devil. Use it wisely and you will be blessed.
