READ THE INSTRUCTIONS
Debbie's laptop broke several months ago, causing some frustration. We couldn't afford right now to put it in the shop, so we decided to attempt repair. We found a hard drive for really a great price, so we purchased and installed it into the drive bay.
Suppose I failed to follow the instructions to make it useable? To format or install operating system? To install Windows or other necessary software programs? It would've been useless!
Mistakes are made because we don't read, study, and meditate on our Set of Instructions: God's Word.
