When you look back over every door opened, every battle survived, every prayer answered, and every moment you should not have made it through, sometimes the only explanation you need is, "Nobody but God!"
Being a Christian is a daily walk of faith, obedience, love, and surrender, so ask yourself whether you are consistently practicing what you profess or only showing enough faith for the highlights.
Don't wait until trouble comes to pray; build a constant conversation with God so that when battles arise, prayer is already your lifestyle, His presence is familiar, and your faith is prepared for the fight.
