This question is a no-brainer. With the flashlight you could see a long way ahead and know what to expect as you travel. You wouldn’t be surprised by unexpected obstacles. When you use a lamp only the area immediately around is illuminated and you have no idea what lies further ahead. If there are obstacles you won’t know about them until you reach them.
All of us are in fact traveling on a dark road. We are living our lives in a world that is in darkness because of sin. God has given us a light to guide us but it isn’t the kind we would have chosen for ourselves.
God has not given us a choice between a lamp and a flashlight. He has given us the Bible to be our lamp and we must either walk by its light or walk in darkness.Your word is a lamp to my feet
and a light to my path.
Psalm 119:105 ESV
If you think God is making a mistake you need to consider the fact that God gives us what we need rather than what we want and because he is omniscient he always know what we need even if we don’t. Each day is filled with things that God wants us to do and he wants us to keep our minds focused on these duties. If we knew what was in the future it is possible that we would be so excited over the good things ahead and so worried about the bad that we would overlook the things God wants us to do now.
A lamp reveals enough so that we know the next step we need to take. When we take that step we carry the lamp forward and its light reveals the next step. That is how God’s guidance works. He shows us what our present duty is and only after we carry out that duty does he reveal the next thing he wants us to do. We don’t need to know our future because God knows it and if we obey him he will prepare us for the dangers and opportunities that are ahead. He will give us the information we need when we need it.
