My abilities as a Bible teacher lie somewhere between the kindergarten and first grade but still there are a lot of spiritual first graders around.
In our spiritual quest one of the first things to know is; that GOD is infinite (subject to no limitation or external determination) and man is finite (having a limited nature or existence.)
Being aware of this has created a great gulf between the two. You might say "I already knew that," well I told you this is first grade stuff.
Now, comes upon the scene Jesus Christ who is 100% GOD and 100% man and is the bridge or connection between the Infinite and the finite.
The next bit of information is important; there isn't anything automatic about this process of interaction between the two parties, Jesus being the factor.
The rules for interaction are spelled out in the Bible most clearly if followed.
These rules are established by the Infinite and are to be complied with by the finite in order for the parties to be "hooked up."
The picture that comes to mind is of three people whose hands are extended and the mediator (Jesus) standing in the middle reaches out and takes a hand of each of the two parties joining all three together.
This process can work very well for we have been given the access code (the name of Jesus) for communication with the Father. Except there is one hindrance and you guessed it - - it is disobedience better known as Sin. Sin breaks the connection and must be re-established before prayer can be fully effective.
There is something in the manual concerning this; 1John 1:6-10 So if we say that we share in life with God, but we continue living in darkness, we are liars, who don't follow the truth. We should live in the light, where God is. If we live in the light, we have fellowship with each other, and the blood sacrifice of Jesus, God's Son, washes away every sin and makes us clean. If we say that we have no sin, we are fooling ourselves, and the truth is not in us. But if we confess our sins, God will forgive us. We can trust God to do this. He always does what is right. He will make us clean from all the wrong things we have done. If we say that we have not sinned, we are saying that God is a liar and that we don't accept his true teaching.
According to this we will mess up but on the other hand we can quickly straighten up by having a little talk with Jesus. This concludes this lesson children - - so be good.
