"Whoever has will be given more, and they will have an abundance. Whoever does not have, even what they have will be taken from them." Matt. 13:12 (NIV)
Take a few minutes, and write down every good thing you have in your life. Every day for the next week or two, take one item on your list, and mentally hold it up to God. Just hold it before God in your mind, be focused in your thought on this one thing, and be grateful and feel grateful in your heart. Your blessings will expand. You will get even more.
If at anytime you find yourself focusing on what you don't want, remember to switch your thoughts back to these things for which you are grateful. Focus on them in your mind and feel it in your heart - ask God to meet with you as you do so - and to expand His Presence in you.
Invite the Holy Spirit into your being. Ask God to commune with you. Then pay attention.
