There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.
For it must needs be, that there is an opposition in all things. If not so, my firstborn in the wilderness, righteousness could not be brought to pass, neither wickedness, neither holiness nor misery, neither good nor bad. Wherefore, all things must needs be a compound in one; wherefore, if it should be one body it must needs remain as dead, having no life neither death, nor corruption nor incorruption, happiness nor misery, neither sense nor insensibility.
God will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape
For it must needs be, that there is an opposition in all things
In each of our lives, God preserves our freedom by allowing us to be drawn towards good, but also to be drawn towards evil. There are bounds set so that no temptation will be able to overwhelm us without our consent, but also no force for good will overwhelm us without our consent either. Exactly how far those bounds are placed will vary for each one of us, according to our own personal strengths and weaknesses, but they will always present us with the same opportunity to freely choose.
Thus you may assume that you will always have a reason to remain faithful, and you will always have a reason to turn faithless. You will always live as a person divided, so that then you may choose which half of yourself to follow. There is no mistake in this, it is by design. Thus that the world is a place divided is evidence of a God who is in control, not evidence against it.
