The "don't know" times are God's instrument to drive you deeper into Him, to surrender all self-reliance for a desperate dependency on Him. You may not know which way to go, but you don't have to stand there fearful, paralyzed or marching in circles. Your Lord, your Shepherd is placing His arm inside yours to lead you where you could never go without Him. (from gospel.com)

 Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. Phil.4:6-7
