Read 2 Corinthians 1:9-10
The old motto of soldiers during the Revolutionary War applies to many areas of life: "Trust in God, but keep your powder dry!"
In other words, place your life in the Saviour’s hands, but stay at the ready. Do all that you can to prepare yourself for battle, understanding that the ultimate outcome rests with the Lord God.
To walk by faith does not mean stop thinking. To trust God does not imply becoming slovenly or lazy or apathetic.... You and I need to trust God for our finances, but that is no license to spend foolishly. You and I ought to trust God for safety in the car, but we're not wise to pass on a blind curve....
Acting foolishly or thoughtlessly, expecting God to bail you out if things go amiss, isn't faith at all. It is presumption.
Wisdom says, do all you can within your strength, then trust Him to do what you cannot do.
