This is the unshakable secret of the Lord to those who trust Him- "I will give thee thy life." What more does a man want than his life? It is the essential thing. "Thy life for a prey." This means that wherever you may go, even if it is into fire, you shall come out with your life, nothing can harm it. 

Many of us are caught up in the show of things. All these have to go, but there is something that can never go, the life that is hid with Christ in God. Are you prepared to let God take you into union with Himself and pay no more attention to what you call the great things? Are you prepared to abandon entirely and let go? 

The test of abandonment is in refusing to say- "Well what about these?" Immediately you allow what about these, it means you have not abandoned, you do not really trust God. If you abandon entirely to God, He says at once, "Thy life I will give thee for a prey". When you do, you will be the most surprised and delighted creature on earth. God has got you absolutely and has given you your life. If you are not there, it is either because of disobedience or a refusal to be simple enough and let go of what you call the great things. 

~Jeremiah 45:5
