Genesis 21:1-2 NIV:
Now the Lord was gracious to Sarah as he had said, and the Lord did for Sarah what he had promised. Sarah became pregnant and bore a son to Abraham in his old age, at the very time God had promised him.
Watch the words above: God had opened his mouth years before this story and had made promises to Abraham and Sarah about children. Years rolled by, and it appeared as if the person who promised had forgotten of had lost the power to fulfil his words. Just as we do today, we hear from God but because of delays, issues and pressures, we begin to doubt the full authenticity of what we heard. We begin to subject the awesome God to rational and logical process, thinking that God can be fitted into our narrow, myopic and limited view.
The beautiful words we focus on today are: 'as he had said'; 'as he had promised'; and 'at the time God promised him'. If there is anything to trust, it is the Word spoken by the Word himself. He's speaking himself and placing his name, reputation and life on the line and because he's a jealous God, he will guard his name against all scandals. He has no nature of deceit or double-speak, and he always watches over his words to bring them to fulfilment.
Wait for God's appointed time. There's something amazing about God's timing. When you have waited patiently, you realize that he stepped in at just the right time you needed him most, not when your own time calculation demanded it. We are the ones who have a biological clock for women to give birth, we are the ones who determine a 'shelf-life' for women to get married. We are the ones who seek to elevate budgetting and forecasting over God's timely and adequate provision. While it is important to plan, never forget: nothing beats God's timing and nothing can be better than having God step into your situation at the 'right' time.
Get a Word from God's mouth today and stake your life on it. God already stakes his life and reputation on his Words and you can rest assured that he knows what he's doing. At his own 'set time', he will turn things around for good. Wait for him, wait on him, wait with patience as God declares his nature and power through you. His time of favour is here.
