Where does faith end and the lived reality of God begin?
In Islam, faith is not a leap in the dark. It begins with good reasons. Whoever stays true to that faith and earnestly strives towards God finds that God comes towards them, and conviction turns into lived certainty.
It is often said that faith means holding something to be true without reasons. Islam sees it differently. One should believe nothing for which there is no sound reason. And if reason clearly refutes a belief, one should give it up. Faith in the unseen is therefore not blind acceptance. It is trust that rests on evidence.
This is easy to see at the beginning of a religion. The first believers accept their faith because they have been convinced. They have seen evidence and acted on it. Later, faith is often simply handed down from parents. It then loses its link with action, and it is not rarely misused for vanity and politics. Such faith remains a claim and never becomes a lived reality.
The way from faith to reality therefore runs through action. Someone who believes in God for good reasons begins to live by that belief. They pray, they strive for honesty and kindness, and they keep going even when it is hard. The first verse above promises that God will show such a person His ways.
Faith and reality are not two separate areas with a fixed border between them. Faith is the beginning, and reality grows to the extent that a person remains steadfast. The second verse above describes how God grants such people calm and confidence. What was first a conviction becomes a certainty that is lived.
