Apostolic trips to the new churches do help to encourage the believers. This is when gifts under the apostolic ministry are given to members by the laying of hands. Remember what happen to Timothy. Paul encouraged him to stir up the gift which was given by the laying of hands. You may not be an Apostle to others, but you are to the people who attend the church you have established.
The Apostle Paul used to make visits to the churches he planted and he understood how his ministry worked with other ministries. In 1 Corinthians 3: 6 Paul the Apostle says, “I have planted, Apollos watered; but God gave the increase” (KJV). Paul also explains that the one who water and the one who plants are really one. In verse eight of the same chapter the Bible says, “Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour” (KJV). This means every one of us is accountable to God because he will reward us according to what we do.
As an Apostle to the new church you are in a better position to know exactly what the people need from God. The way you feel for them is different from the way any other person would. There is real connection in the spirit although you may not even be physically present to minister to them. You pray for them from a different perspective. When you progress spiritually they also get the opportunity to progress in life.
This is what a pastor should build on because he also takes a special place in the church after the church planter has left. As pastor in the new church begins to pray and interceded for the people he also starts to have a special connection with the people. A pastor is also like a priest who wore a breastplate on his chest as he ministered in the tabernacle. The breastplate helped to present the people before God and a pastor who prays for the people also presents the people to the Lord.
