Romans 10:9-10 says to be saved (rescued by Jesus for eternal life) you have to BELEIVE (100% commitment to Jesus in faith and actions) and SAY with your mouth, JESUS IS LORD, then you will be saved. The Books of James says faith without works is dead (or faith without corresponding actions and words is dead). God answers all who will cry out to Him to be saved. However, once we are saved, He expects us to not stay baby Christians all our lives but grow in faith and love each day as we daily study the Holy Bible.
Some Christians say ‘ I have done good deeds, why is God not answering my prayer request?’ James chapter 1 says if you doubt you will do without. You my ask God for a promise in the Bible but if you doubt or do not have corresponding actions and words in line with your prayer request, you may be missing out. People often ask Jesus for something and then they start talking things contrary to what they have just asked for. Learn that you words are so powerful and are recorded before God. The Bible says many things to watch what we say such as:
1) we will give an account of every idle word
2) life and death are in the power of the tongue
3) By your words you will be justified and by your words you will be condemned.
Mark 11:22-25 also has explains it clearly saying 3 times the importance of the words we say. So if you are standing on a Bible promise, let your words be filled with faith and your actions be filled with faith. If you doubt, repent quickly asking Jesus to forgive you and get your faith, words and actions back again on the Bible promise you are standing on. If you develop a passionate prayer life with Jesus, He will also show you other reasons that could be hindering your prayer request such as: 1 Peter 3:7, Malachi 3:8-11, Hebrews 11:6, James 1:22.
