Many people in this world, even Christians today, think that they have to seek God, that they have to run and find Him.
Under the Old Covenant, the Israelites did have to seek God, yet seeking God was all about the sacrifices made at the Temple.
God in fact cannot be sought in that He holds everything together.
What does separate us from Him, our sin, has been taken away forever at the Cross.
Jesus did not shout at the Cross: "Why have you forsaken me?" for nothing:
"And at the ninth hour Jesus cried with a loud voice, saying, Eloi, Eloi, lama sabachthani? which is, being interpreted, My God, my God, why hast thou forsaken me?" (Mark 15: 34)
Why did God forsake Jesus at the Cross? Because He became sin in our place:
"For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him." (2 Corinthians 5: 21)
God cannot look on sin:
"Thou art of purer eyes than to behold evil, and canst not look on iniquity: wherefore lookest thou upon them that deal treacherously, and holdest thy tongue when the wicked devoureth the man that is more righteous than he?" (Habakkuk 1: 13)
And we cannot stand in God's presence if our sins are not take away:
"O LORD God of Israel, thou art righteous: for we remain yet escaped, as it is this day: behold, we are before thee in our trespasses: for we cannot stand before thee because of this." (Ezra 9: 15)
Today, because Jesus took away all our sins, and died as us for our sin, God does not have flee from us or reject us, but rather He runs to us.
"Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee." (Hebrews 13: 5)
Because of Jesus, you and I do not have to run after God or try to seek Him out, but we can know and believe that He is running after us.
