There are many ways to build your Faith. The best way is to gain an understanding of God's will and way. It all depends on what you value in life. Your actions and decisions define your character. Examine yourself.
Spend Time With God
Start a journal of questions that you may want God to answer. Pray, and read the scriptures. Whatever scriptures speaks to your situation write them down. You may be tempted to give up because sometimes God is silent, but don't give up. Remember this is for your spiritual growth, and building your faith. Continue to listen for God's voice through His Word; hear what He has to say to you about you. Believe in His promises. Ask God to help your unbelief. Enjoy every precious moment in God's presence. When you accomplish reading one chapter begin another. The more time you spend in and with the Word of God the more confident you become in your faith and trust toward and in Him. You'll be telling yourself, 'I can do all things through Christ who strengthens me (Philippians 4:13).
Face Your Fears
Fear hinders your growth in all areas. "For God has not given us a spirit of fear and timidity, but of power, love, and self-discipline (2 Timothy 1:7). Whatever it is that you are afraid of face it. You'll realize that facing your fears with God builds faith. Free yourself from inhibitions. Allow your mind to process the whole experience in order to respond and or react appropriately. If God be for us who can be against us? (Romans 8:31). You may not turn into a one man army, "But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint (Isaiah 40:31).
