If we as infants need love, care, guidance and protection to learn the basic of just walking and talking. Why do we expect those that are new in their faith should automatically know how to walk, talk and act in their new found faith in God.
We should teach them to read the Word of God, to go to him in prayer when they need help and show them how God has guided us in our own lives. The majority of the New Testament is instruction for the new believers. If it took such lengthy instruction to help guide them. How can we expect someone who just surrendered their life to God to know everything.
We need to love and encourage them to learn about God and develop their own relationship with him. So that he can father them to be who he made them to be. Teach someone to walk and talk as Jesus. Just like Jesus taught you!
