How can I strengthen my faith in God ? I don't have much knowledge either. ?

Start of having faith in GOD , the Lord of all the worlds , then learn more how to practice the only religion of GOD, send down for all mankind from the beginning till the end of the world, so that you would become successful both in this world and the here after world. 

According to the Bible, it is possible to have a close personal relationship with God. The Bible states that God called the Hebrew patriarch Abraham “my friend.” (Isaiah 41:8) God invites all of us to draw close to him and whish to draw close to us: "Draw close to God, and he will draw close to you" - James 1:5  

God also invites us to pray to him, and he is always ready to listen to our prayers. "No matter what we ask according to his will, he hears us." - 1 John 5:14. "Cast all your anxiety on him because he cares for you" - 1 Peter 5:7 "In fact, [God] is not far off from each one of us.” - Acts 17:27 

Below are some practical steps that will help you to strengthen your faith and improve your relationship with God:

1.) Gain More Knowledge of God and Jesus

"How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? " - Romans 10:14

“This is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent..”​—John 17:3.

2.) Read the Bible (especially the Gospels) every day

“All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight.”​—2 Timothy 3:16.

3.) Meditate on Jesus life and teachings

"I remember you while upon my bed; I meditate on you during the watches of the night" - Psalm 63:6 

"Ponder over* these things; be absorbed in them, so that your advancement may be plainly seen by all people." - 1 Tim 4:15

4.) Pray for faith

"If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him." - James 1:5

"Now the apostles said to the Lord: Give us more faith." - Luke 17:5

5.) Experience Gods presence in your own life

"Come near to God, and he will come near to you. Clean up your lives, you sinners. Purify your hearts, you people who can't make up your mind." James 4:8

"Anyone who loves me will obey my teaching. My Father will love them, and we will come to them and make our home with them" - John 14:23

Practicing and hearing the word of God.

James 4:8

Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded.

Romans 10:17

So belief cometh of hearing, and hearing by the word of Christ.

Get knee pads  Pay your tithe, eat the cookie, and drink the wine.

 buy a candle, visit the Pope. Never turn your back on the Priest.

Do a mass five times a day.

Keep your ignorance, or you might become an atheist.

Start obeying all of Jesus' sayings .

Death leads to heaven or hell.  The Lord Jesus Christ is God, who died on the cross and shed His blood to pay for all of our sins in full, and then Jesus was buried, and then Jesus resurrected from the dead.  Nothing you could do will ever pay for any of your sins.  Jesus already paid for all of our sins with His death on the cross and His shed blood, and then Jesus resurrected from the dead.  So the only way to get into heaven and avoid hell, is by believing in the Lord Jesus Christ, without adding any of your own works.  See Romans 4:5.  It is too late for you to be saved, after death.

Read the Book of John.  Use the King James Bible because it is 100% perfect. The Bible is the Word of God.

Romans 10:17  So then faith cometh by hearing, and hearing by the word of God.

I would recommend reading the Bible and praying daily.

YOU CAN ASK JESUS FOR STRENGTH AND GUIDANCE. READ THE NEW TESTAMENT UNLESS U WISH TO BEGIN WITH THE OLD TESTAMENT..

Rom 10:17  So faith comes from hearing, and hearing through the word of Christ. 

No worries . You will know everything you need to know the day you kick the bucket .
