I created a blog on here to answer this very issue. Please take a look.
Psalm 66:18 If I cherished sin in my heart, the Lord wouldn't have listened.
Proverbs 34:15 The eyes of the LORD are on the righteous and his ears are attentive to their cry
Proverbs 1:25-26 Since you ignored all my advice and would not accept my rebuke, I in turn will laugh at your disaster; I will mock when calamity overtakes you. when calamity overtakes you like a storm, when disaster sweeps over you like a whirlwind, when distress and trouble overwhelm you.
Proverbs 21:13 Whoever closes his ear to the cry of the poor will himself call out and not be answered.
2 Chronicles 7:14 If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land.
It's important to note that believers are considered blameless to God (Ephesians 1:4 "For he chose us in him before the creation of the world to be holy and blameless in his sight. In love" and again I Corinthians 1:8 "He will keep you strong to the end, so that you will be blameless on the day of our Lord Jesus Christ.") although at this point there may be uncertainty whether that means on the old earth (here), or once we are tried with fire by the Holy Spirit and every good work in us is perfected. We know however that we are still growing according to Colossians 2:7 "...Then your faith will grow strong in the truth you were taught..." And we may be strong or weak according to Ephesians 6:10 "Finally, be strong in the Lord and in his mighty power." God's grace covers over our sins completely as believers, so we are treated as royalty as long as we own our faith, as long as we act like we're royalty, as long as we trust that God is good and He is for us. 1 Peter 2:9 But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light. 1 John 5:4 For everyone who has been born of God overcomes the world. And this is the victory that has overcome the world—our faith.
My conclusion is this, you activate your faith by trusting God at His word, by believing it beyond your current circumstances, through prayer trusting God that it will come to pass.
Mark 11:24 Jesus: "Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours."
