All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
Life is going to be tough, it will be hard. Accepting Christ into your heart isn't some magic pill that makes the bad stuff all go away and grants prosperity. Christians have hard times, just like anyone else.
Christians fall into sin over and over and over. Do you know when that is? When they are out of God's word. When we decide we are above God, we are smart enough, we are good enough to make it on our own.
But we can't. We cannot do it on our own. We are not above God, and we cannot face the challenges of life successfully without Him.
Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
What did Jesus do when He faced trials and temptations? When he was tempted, every time, He quoted the Word of God.
Every Christian should be able to quote scripture, should be able to defend at the very least John 3:16.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
We'll continue this discussion tomorrow, with some more scriptures about prayer, the Word of God, and battling temptation and trial.
