No one can improve on that plan.
Once you accept Jesus as your savior you are born again. Everything you need will be provided by your faith and grace.
For even when we were with you, we gave you this rule: “The one who is unwilling to work shall not eat.” 2 Thessalonians 3:10
Anyone who does not provide for their relatives, and especially for their own household, has denied the faith and is worse than an unbeliever. 1 Timothy 5:8
