You never know when God may call you into something new.
Consider Abraham...
At 75 he was minding his business in a place called Ur when God called him to go to Canaan.
Abraham didn't know what it was all about, but in faith he took steps to follow and became the father of nations.
Don't let your ordinary routine keep you from hearing God's call.
And with the faith of Abraham follow wherever the Lord leads.
You never know what might come of it.
In every generation the children of Abraham are to "put their confidence in God, not forget God's works, and keep His commandments" (Ps.78:7).
