Since believing is looking it can be done any time . No season is superior to another season for this sweetest of all acts. God never made salvation depend upon new moons nor holy days or sabbaths. A man is not nearer to Christ on Easter Sunday than he is, say, on Saturday, August 3, or Monday, October 4. As long as Christ sits on the mediatorial throne every day is a good day and all days are days of salvation.
Neither does place matter in this blessed work of believing God. Lift your heart and let it rest upon Jesus and you are instantly in a sanctuary though it be a Pullman berth or a factory or a kitchen. You can see God from anywhere if your mind is set to love and obey Him.
