This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.
Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful.  But his delight is in the law of the Lord; and in his law doth he meditate day and night.  And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper.Psalm 1:1-3
To do these things, you need the power of the Holy Spirit in your life. When I received the baptism of the Holy Spirit, it changed me forever. I know from experience that a believer wasn't going to get very far without the power of the Holy Spirit.
All of these promises, and really everything in the Word of God, are for you, but you have to be conscious of them. You have to renew your mind, and you have to be aware of these things. It's not a matter of God's faithfulness; it's a matter of your faithfulness to Him and His Word. You've got to get to where you are laser focused on God. He longs for you to abide in Him and to see you prosper and succeed. I promise that when you abide in Him, it changes your heart, touches God's, and causes you to bear much fruit. It does something for you and to you. These materials will be a blessing to you or someone you know.
