The battle of truth is real; and it seems that this battle is intense. As we look at this battle we need to put some things into perspective. The first is that we are Christians. Followers of the Lord Jesus Christ. To keep it simple, God(The father, The one true God...) revealed to you/me His Son Jesus, the Gospel message, and we 'believed'. 'By faith..." As a result of this faith/belief/trust in Jesus Christ our ways of life, ways of thinking... changed; from worldly to heavenly.
Some of these changes come without effort(foul language stops...) but some comes slowly with learning and revelation. Now that learning and revelation comes through reading God's word, the Bible. This learning and revelation is to bring us to 'Heavenly Thinking and actions' or Godly thinking...
The attack of truth for the Christian usually is the attack on the Word of God. Be it not relevant, be it not for our time, be it not real, be it not really meant that way, be it out dated, be it that it does not matter, be it that's the old testament, or God did not mean it, and the list goes on and on.
This attack is so prevalent that it starts right at the beginning of the Word of God. Creation. Even now in our modern era, 'scholars' are trying to explain miracles of God; using science and human understanding... "Here's how God did it" As a result 'whittling away' the believer's faith. This is how the attack works, a little unbelief of a small thing, a little lack of trust in God... Oh a little of the world mixed with the truth of God. Then the things of God are no longer really important and next thing God is not important; even though we are going through the motions... We are going to church... doing christian works... (notice the small c) we are self fulfilled but something is missing. We are doing the motions... but not stopping to be with our God and Lord Jesus Christ. Not taking the time for God to refresh us... Not taking the time for God to chastise us... Not taking the time for God to teach us...
One must never forget, 2Tim.3:16a "All scripture is inspired by God,"
