I don't know the proper words for all that is important to say. But, I do know that a relationship with God through Jesus Christ is the most important part of living here on earth. I do know that God wants us to have a full and fulfilling life both now and for eternity. I do know that God changed my life through His grace.
Getting into a right relationship with God is straightforward. What is needed to accept God's free gift can be summarized in a bunch of different ways; here is one that makes sense to me.
Dear Lord, I believe that you are the Son of God and that you died on the cross for me. I know that I have been disobedient to you and that I need your forgiveness. I turn from my sins right now and receive you as my Savior and Lord. Thank you for saving me!
If you prayed that prayer or one like it: Congratulations!
It is important that you connect with others who also have made that step of faith. Perhaps that may be through your local church -- but, maybe not. Here are a couple of links to groups that offer some free resources.
