In the beginning, God made everything good, good and very good. The world was full of amazing wonder and beautiful things. There was no disorder, ruin, or decay: no weeds, stickers, or any bad smells. The amazingly perfect first man and his beautiful wife ruled over it all in peace, pleasure, and delight.
In the Garden of Eden were two trees, the Tree of Life and the Tree of the Knowledge of Good and EviI.
Man opened the door to evil on earth by eating from the forbidden tree. The blessing (happiness from God) was gone and ruin began. God then promised to rescue them.
Man fell from what God designed by not listening to God, the way back into paradise blessings was by listening to God.
God desires with all His heart to rescue and bless man. But man is made in the image of God and therefore is free to choose. Every day we choose to listen to God or evil.
We listen to God by hearing His word: the Holy Bible.
(The Holy Bible is the only book on earth that is from God. "All scripture is God-breathed" says 2 Timothy 3:16 and "Holy men of God spoke as they were moved by the Holy Spirit says 2 Peter 1:21.)
When we listen and believe what He says, He brings us into lives of great blessing.
When we trust what He says, that's faith. He has put all truth in His word.
"Your word is truth," Jesus said in John 17:17.
The voice of evil is also present in the world. We are following one or the other.
"Without faith it is impossible to please Him." Hebrews 11:6
"Faith comes by hearing the word of God." Romans 10:17
