God wants to be and should be involved in every area of your life. Therefore, we should pray about all things and not be so foolish to think that our own feeble strength is sufficient to handle even the smallest of tasks without the power, wisdom and presence of God.
As Christians, we should be praying about every decision we make and every circumstance we face. Whether it is big or small, significant or insignificant, let us not hesitate to pray for wisdom, guidance, to be filled with the Spirit and for God's will to be done in our lives and through us (as His vessels) for His glory and for the advancement of His kingdom.
Let us not underestimate our Lord's sovereignty and power. Let us remember that He can use any opportunity and situation to bring glory to Himself (and so He should).
