It would seem in ourselves we have a faith tank. A place where our faith is stored and something we draw upon when we need it. Some days we feel we are full of faith and can face every thing that life gives us. And there are some days that we feel we can not even lift a piece of paper or carry ourselves.
When do we sense we are full of faith ? when we have spent our time in prayer and have our daily devotion. And when do we feel empty ? When we have neglected prayer and devotion, when we got distracted by the ways of the world, when we allow pride and greed and lust enter our thoughts and action.
How do we keep ourselves full of faith ? Through confession and prayer, being close to Jesus by reading and meditating on the word of God as recorded in the Bible. Through fellowship with fellow Christians who loves the Lord.
Even our Lord Jesus when He was in human form spent time in early morning prayer. When a woman with an issue of blood touched the hem of His garment, Jesus felt that virtue flowed out from Him.
It would seem there is really a faith tank and let us keep it full and do not let it run dry. But in case we got stranded when our faith is empty, always call on Jesus because He is faithful.
