But like it said it is nearly impossible for humans. Jesus can do it, that's why he is sinless.
When humans get really angry, it is almost 100% chance that they will sin. It is a sin to not forgive that cheating BF/GF
by sun down, because it is
God's will that you forgive that person by sun down.
Heck if you do not forgive that cheating BF/GF
on the spot instantly you probably (I am not 100% sure on this) already sinned, because as you guys guessed it is probably
God's will that we forgive our cheating BF/GF on the spot. (Let's hope we never get one of these cheaters in our lives.
) We know this because
Jesus always forgive on the spot, just like he did for that woman caught in the very act of adultery.
If we want to be like Jesus and be his followers,
these are the kind of "crosses" that we have to carry and follow him.
Of course the same thing applies to the rest of Ephesians 4, that
they are all ideals but almost impossible. Ephesians 4:29 for example say we should never speak any kind of corruption (discouraging), but only to build other people up (encouraging) to give grace to everyone. Well sometimes we speak corruption before we even realize it.
My point is for
certain sins they happen so fast that we did it before we even know it. In other cases the
temptation and sin happens so automatically, right afterwards, that we cannot stop it. But that is ok. That's why we all need Jesus. Of course we never stop trying our best each day.
