@Brittany_Bowman1 brought up this question in another thread. Here are some initial thoughts.
Jesus Did Not Leave Us as Orphans - The Holy Spirit
In Christianity, God is very involved int he world! Jesus came to earth to show us how to know God and be known by Him - Jesus is ‘God with us’. And when Jesus left the disciples, He promised to send another Helper - the Holy Spirit - who would guide us into all truth. Jesus did not leave us orphans, but His Spirit guides and strengthens us as we do God’s work on the earth.
Matthew 28:20 - And surely I am with you always, to the very end of the age.
John 14:15-21 If you love me, keep my commands. 16 And I will ask the Father, and he will give you another advocate to help you and be with you forever— 17 the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you. 18 I will not leave you as orphans; I will come to you. 19 Before long, the world will not see me anymore, but you will see me. Because I live, you also will live. 20 On that day you will realize that I am in my Father, and you are in me, and I am in you. 21 Whoever has my commands and keeps them is the one who loves me. The one who loves me will be loved by my Father, and I too will love them and show myself to them.
God is Always At Work
The Bible is clear that God is at work in history, drawing men unto Himself and reaching out to them that they might know Him. At just the right time in history, God sent Jesus so that all men and women may become sons and daughters of the living God. God may not work on our time scale or in the way we want Him to, but He is always working. He is not distant or aloof from the affairs of the world.
Acts 17:26 - From one man he made all the nations, that they should inhabit the whole earth; and he marked out their appointed times in history and the boundaries of their lands.
2 Peter 3:9 - The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance.
Galatians 4:4-7 - But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, 5 to redeem those who were under the law, so that we might receive adoption as sons. 6 And because you are sons, God has sent the Spirit of his Son into our hearts, crying, “Abba! Father!” 7 So you are no longer a slave, but a son, and if a son, then an heir through God.
