2 John 1:4 I rejoiced greatly to find some of your children walking in the truth, just as we were commanded by the Father.
The word find used in this scripture translates: I find, learn, discover especially after searching.
In the scripture above children are referred to in the Greek text as anyone living in full dependence on the heavenly Father, fully (willingly) relying upon the Lord in glad submission. This prompts God to transform them into his likeness. A child living in utter dependence upon the Lord drawing guidance from our heavenly Father that gladly submits to the Father's plan.
We completely learn this, as we are sensitive to Christ speaking His rhēma-word within to impart faith. When we walk in the truth of God's Word we will abide in Him and He will abide in us. We have to fellowship with Him and the right relationship to know when we ask of Him in prayer he will answer us because Jesus knows who we are.
May bible teachers have come down very hard on the believers and try to beat them into submission to the Lord, when in fact they are causing them to go the opposite direction because the Love of the Lord is not in the words or the message. They are actually performing a form of witchcraft called (manipulation). You have to see the only one who can draw us to the father is the Holy Spirit, Word of God, Truth, and Love of the Father.
If we can be like the children mentioned here in this passage then we would not have to go through all the confusion and pain of walking in the flesh.
