Hello! I totally understand your concern. We as christians are excited to share something that we feel so blessed about. And I am sure, a lot of people who aren't christians are very interested to hear us. Of course, because we are not forcing anyone to listen!
For example for a few times people have asked me whether I am a christian, even when I had not told them about my faith.
But dear friend, do we have to have a feeling of "sensing the presence of God", when we know for sure God is by our side? When you were alone in your prayer room, God promised to stay with you wherever you might go, and He doesn't break His promises but He stays loyal.
I heard someone wise say that God works in people's hearts even before we approach them (like in the example of Acts 8:26-40). And it makes sense to me!
2 Timothy 2:11-13
11 This is a faithful saying: For if we died with Him, We shall also live with Him.
12 If we endure, We shall also reign with Him. If we deny Him, He also will deny us.
13 If we are faithless, He remains faithful; He cannot deny Himself.
Matthew 6:6
But you, when you pray, go into your room, and when you have shut your door, pray to your Father who is in the secret place; and your Father who sees in secret will reward you openly.
Acts 8:29-35
29 Then the Spirit said to Philip, "Go near and overtake this chariot."
30 So Philip ran to him, and heard him reading the prophet Isaiah, and said, "Do you understand what you are reading?"
31 And he said, "How can I, unless someone guides me?" And he asked Philip to come up and sit with him.
32 The place in the Scripture which he read was this: "He was led as a sheep to the slaughter; And as a lamb before its shearer is silent, So He opened not His mouth.
33 In His humilation His justice was taken away, And who will declare His generation? For His life was taken from the earth."
34 So the eunuh answered Philip and said, "I ask you, of whom does the prophet say this, of himself or of some other man?"
35 Then Philip opened his mouth, and beginning at this Scripture, preached Jesus to him.
