This reading from the Book of Exodus, which tell the story of Moses and the taking of the Israelites out of Egypt, contains a verse which sums up all the work of God in our lives.
"Have no fear! Stand firm, and you will see what the lord shall do to save you today: the Egyptians you see today you shall never see again. The Lord will do the fighting for you: You only have to keep still!"
We are told to trust God and not have fear. Stand firm; really trust, no matter what, and watch the work of the Lord in our life. The Egyptians, those things in life which we fear such as sin, addictions or whatever, if we believe and trust, God shall take them away and even more, he shall do the fighting for us.
What must we do? Trust and stand firm. Its as easy as that! ... But that ain't easy.
