God has certainly been with you throughout this situation, not only preserving your life but also restoring you to health. You can say with the writer of the Psalms in the Bible, "Though I walk in the midst of trouble, you preserve my life" (Psalm 138:7).
My question to you, however, is this: Why did God do this for you? The reason, I believe, is so you could come to know Him in a personal way and commit yourself to His plan for your life. God loves you -- whether you love Him or not, or whether you even believe in Him or not. Your accident was a tragedy, but an even greater tragedy would be for you to forget God's goodness to you and spend the rest of your life apart from Him.
God has been good to you, delivering you from death or serious disability. But God has been good to you in a far greater way by sending His Son into the world to take away your sins and make you part of His family forever. We are separated from God because of our sins, but when Jesus died on the cross, all our sins were transferred to Him, and He took the judgment we deserve.
Take time to thank God for being with you during these months. But most of all, thank Him for sending Jesus Christ into the world so you may be cleansed of your sins and given a new reason for living. Commit your life to Him today.
