In every Christian there is the Holy Spirit that speaks to that one in times of trouble or distress.
We sing the song 'He Whispers Sweet Peace To Me', but do we truly believe that even in those times when we are backed in to a corner that God's Holy Spirit is indeed assuring us that He is there?
Corrie Ten Boom's sister Betsy did indeed put the family and all in the house in harm's path because of her willingness to listen to the Holy Spirit and not to the flesh.
Yes, the flesh is indeed weak, but sometimes we use that verse as a cop-out. 'I just could not help it' seems to be the general excuse. God's Word says,
1 Corinthians 10:13 (KJV) 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]. {common...: or, moderate}
We do not have to give in to those temptations to lie, cheat, steal, kill, covet, whatever the temptation may be. God has made a way of escape. If you are of God, His Spirit is there to strengthen you even during the hardest trials of life and set you on the other side.
Yes, I know many are saying it is easier to say than to do, but if you trust Christ in those situations, He will make it easy to get through.
Look at the many martyrs down through history who could have saved their own lives if they had just bowed to man; but instead, they obeyed Christ and He strengthened them even at the time of death.
Backed into a corner is an excuse, yes. But it is a weak excuse since God has assured us that He would not allow on us more than we can bear.
