Many years ago as I began working as an electrician in a Pennsylvania steel mill, I gained some advice from an older man as we were climbing on a crane some 50 feet in the air. He told me that in order to keep from falling, I should keep three things in contact with the crane at all times: two feet and one hand or two hands and one foot. It didn’t matter which. He further stated that with three in contact, if one contact was was to be lost, you still would have two firm contacts remaining. If you only had two contacts and one was to be lost, you most likely would not be able to maintain your position and would more than likely fall. I eagerly took his advice.
Similar advice can be given so as not to fall spiritually. The psalmist states that a good man will not be afraid of evil tidings because his heart is fixed, trusting The Lord (Psalm 112:7). His heart being fixed has the idea that his heart is firmly established in The Lord. It also carries the idea that it is in a ready state.
You can be sure to keep from falling if you established your heart in The Lord. Trials may come and attempt to remove your secure footing, but a heart that is set in The Lord will continually run to him for refuge and not fall into the pit of hopelessness and despair.
You can establish your heart in the Lord by attending to his word (Proverbs 4:20). You can also establish your heart by removing sources of negative influence (Proverbs 4:23-24). Between pushing away the world and its philosophy and drawing your heart nigh to God, you will secure your footing so as not to fall.
