Our first most precious spiritual exercise as true believing Christians is taking time everyday to talk, thank, and worship God through prayer in Jesus name. This fellowship and communion with God is where He blesses us with cleansing power of forgivnness through the precious sacrifice of His son, and where He receives our petition for both blessings and protection. But most importantly our praise and gratitude for His salvation through His only begotten Son Jesus Christ, followed by our praise for His awesome creation, His omnipotence, Holyness and loving kindness. For which He deserves all our praise and worship. Our second most important exercise is to study and meditate on the Word of God, which is our double-edged sword against the enemy, used by Jesus himself on every encounter with satan and the against religious structure that did not recognize Him as their Savior.
James 5:16-18 "So then confess your sins to each other and pray for each other so that you may be healed. The earnest prayer of a righteous person has great power and produces wonderful results. Elijah the prophet was human as we are, and yet when he prayed earnestly that no rain would fall, none fell for three and a half years! Then, when he prayed again, the sky sent down rain and the earth began to yield its crops... But when you ask in prayer, be sure that your faith is in God alone. Do not waver, because a person with divided loyalty between Jesus Christ and the cares of this world is as unsettled as a wave of the sea in a storm that is blown and tossed by the wind. James1:6
