Just as a newborn baby in the natural needs to be taken care of until it grows/ matures enough to be able to grow on their own, so does a baby christian until they are full grown.
God provides for His children just as parents take care (well are supposed to) of their children.
Eph 4:1 I, therefore, the prisoner of the Lord, beseech you to walk worthy of the calling with which you were called,
Eph 4:11 And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers.
Rom 12:1 I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.
:2 And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
:3 For I say, through the grace given to me, to everyone who is among you, not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith.
:4 For as we have many members in one body, but all the members do not have the same function,
:5 so we, being many, are one body in Christ, and individually members of one another.
:6 Having then gifts differing according to the grace that is given to us, let us use them: if prophecy, let us prophesy in proportion to our faith;
:7 or ministry, let us use it in our ministering; he who teaches, in teaching;
:8 he who exhots, in exhortation; he who gives, with liberality; he who leads, with diligence; he who shows mercy, with cheerfulness.
:9 Let love be without hypocrisy. Abhor what is evil. Cling to what is good.
1 Cor 12:1 Now concerning spiritual gifts, brethren, I do not want you to be ignorant.
1 Cor 12:8 for to one is given the word of wisdom through the Spirit, to another the word of knowledge through the same Spirit.
:9 to another faith by the same Spirit, to another gifts of healings by the same Spirit,
:10 to another the working of miracles, to another prophecy, to another discerning of spirits, to another different kinds of tongues, to another the interpretation of tongues.
:11 But one and the same Spirit works all these things, distributing to each one individually as He wills.
1 Cor 12:28 And God has appointed these in the church: first apostles, second prophets, third teachers, after that miracles, then gifts of healing, helps, administrations, varieties of tongues.
1 Tim 4:14 Do not neglect the gift that is in you, which was given to you by prophecy with the laying on of the hands of the eldership.
2 Tim 1:6 Therefore I remind you to stir up the gift of God which is in you through the laying on of my hands.
