Great faith isn't something that happens by accident; faith starts very small, and only grows over time. And -- like the flowers or vegetables in your garden -- it only grows if we take steps to make it grow. Jesus once compared faith to a mustard seed, which, "Though it is the smallest of all your seeds, yet when it grows... becomes a tree" (Matthew 13:32).
What is your friend's secret? The key (I suspect) is that she has a close personal relationship with God -- a relationship that has grown stronger over the years. She knows God is her friend -- and because He is her friend, she can share every concern and burden with Him. It began when she committed her life to Jesus Christ, and it grew stronger as she learned to trust Him and walk with Him every day.
This can be your experience -- and I pray it will be. By a simple prayer of faith, ask Christ to come into your life today -- and He will. Then get to know Him by making His Word, the Bible, part of your life every day. Pray, too, about everything that concerns you -- and thank Him also for every good thing He gives you.
In addition, seek out a church where you can grow spiritually -- a church where Christ is preached and lived. The most important decision you will ever make is your decision for Christ. Make that commitment today, and then make it your goal to "grow in the grace and knowledge of our Lord and Savior Jesus Christ" (2 Peter 3:18).
