Psalm 31
5 Into your hands I commit my spirit;
redeem me, O LORD, the God of truth.

Where have you heard this before? Yes, from the lips of Jesus on the cross. It is interesting how we have the first part quoted, but not the second. God is the God of truth, but Jesus already knows that about himself. If God is truth then honesty will always bring you back to him if you are seeking other truths. When Christians stray it is not because God has a "truth" problem; it is because the Christian has a problem with wanting to follow the truth.

"When it comes to truth, either there is truth or there isn't. If there isn't truth, then you are still trusting in the truth that there is no truth." Think about this.
