It is good that you should know that God, the One True God of Creation is the Source for those who seek to prepare. To prepare without seeking God's Guidance and God's Direction is not unlike those who sought to build the tower to reach heaven after the great flood. Those who turn to God and seek God's Guidance for preparation are like God's Servant known to man as Noah.
"God is looking for men and women... WHO WILL TAKE UP THE CROSS DAILY and FOLLOW JESUS, and thus manifest in their lives and in their service the reality of those words, 'It is no longer I, but Christ that lives in me.'" This, and this alone is the Spirit-filled life." ~ Zac Poonen
