Joshua 1-5: Going Out and Comng In

So when the people broke camp to cross the Jordan, the priests carrying the ark of the covenant went ahead of them. Now the Jordan is at flood stage all during harvest. Yet as soon as the priests who carried the ark reached the Jordan and their feet touched the water’s edge, the water from upstream stopped flowing. It piled up in a heap a great distance away, at a town called Adam in the vicinity of Zarethan, while the water flowing down to the Sea of the Arabah (the Salt Sea) was completely cut off. So the people crossed over opposite Jericho. The priests who carried the ark of the covenant of the LORD stood firm on dry ground in the middle of the Jordan, while all Israel passed by until the whole nation had completed the crossing on dry ground. - Josh. 3:14-17 NIV

The entire journey of the Children of Israel, from captivity in Egypt to entering the land promised to their forefathers, was bookmarked by two identical events:  the crossing over of vast bodies of water on dry land.  First God parted the Red Sea as they were fleeing Egypt, then God parted the Jordan river when it was running at high tide so they could cross over into Canaan.  The mighty hand of God preserved their leaving and entering, just as the Psalmist noted in Psalms 121:  The LORD shall preserve your going out and your coming in from this time forth.  Ps. 121:8 KJV

God has not changed.  He still preserves our going out and coming in.  He dictates and even reveals when it is time for us to leave any given situation, whether it be a bad relationship, a bad job, a toxic family situation, or the wrong neighborhood.  He tells us when it is time to go and leads us to our next destination.  That doesn't mean that every time we get frustrated with a situation, we should pack up and leave.  In fact, it is usually the opposite.  We are not to run willy nilly from one bad situation to the next.  We are to wait on him.  When he tells us to move, we are to move, not before.  If we fail to wait for him, we cannot trust that he will be there in our going out and coming in.
