Most products sold in our stores have to go through a battery of various tests in the laboratory to see if they can truly do what they are designed to do. It only after these tests that we can be sure it will perform as it has been advertised. When you buy it, you want to be assured of quality. When a person puts their faith in God, that faith is going to be tested.. mainly because God wants us to know that He will be true to the promises He has made. Peter puts it this way in 1 Peter 1:7 " That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ". Not only do you need to know that God can do what He said and that "He will never leave you nor forsake you", but there are others around you who are watching to see if your faith in Christ is just words or if it is genuine and from the heart. People will many times let us down, but our faith has to be anchored in Jesus Christ. Don't allow problems and difficulties keep you from growing in your walk with God.
