If you have believed in Jesus and received Him as your Saviour and doubt it’s impossible to grow in Christ.
Your faith is not based on your changing feelings but on the unchanging Word of God. God assures your salvation in His Word.
Romans 10:9 says “If you have confessed and believe, then according to God’s unchanging Word the matter is settled. You are Saved.
You can receive Christ right now by faith through prayer.
Prayer is talking to God. God knows your heart and is not so concerned with your words as He is with the attitude of your heart.
The following is a suggested prayer. If this prayer expresses the desire of your heart, then you can pray this prayer right now and Christ will come into your life, as He promised.
Lord Jesus, I need You. Thank You for dying on the cross for my sins. I open the door of my life and receive You as my Savior and Lord. Thank You for forgiving my sins and giving me eternal life. Take control of the throne of my life. Make me the kind of person You want me to be.
