Psalms 78: 40 How oft did they provoke him in the wilderness, and grieve him in the desert! 41 Yea, they turned back and tempted God, and limited the Holy One of Israel.
Unbelief can stifle achievement, and it can cause persons to set a very low bar for themselves in life, as well as preventing some from reaching their full potential. It can cause persons in many instances to suffer from low self-esteem, it creates, and fosters doubt, and it can anticipate, and actually produce many real or phantom troubles, that are entirely imaginary.
But worst of all, it can produce doubt about God’s ability to do as He has promised, and it could often cause persons to limit God to mere finite modes of thought and action, essentially bringing Him down to the level of mortals, when it comes to what He can do. And because of this, one of the by-products of limiting God is that our expectations of Him are greatly reduced.
According to the scriptures, unbelief does not only affect unbelievers, for the syndrome can be found in the lives of many righteous persons, who had a stellar record otherwise, but faltered at some point in their experience through indulging unbelief. Faith believes all things and hopes all things, but unbelief casts a dark shadow of doubt wherever it goes.
Psalms 78:42 They remembered not his hand, nor the day when he delivered them from the enemy.
May The Lord add His blessing to the study of His word. God bless!
