Then after fourteen years I went up again to Jerusalem with Barnabas, taking Titus along with me.  I went up because of a revelation and set before them (though privately before those who seemed influential) the gospel that I proclaim among the Gentiles, in order to make sure I was not running or had not run in vain.
He came back to Jerusalem after a direct revelation from God and not because any man told him to do so.
He did not sit around. He left Jerusalem 14 years prior and was was busy spreading the gospel. He then came back because he was acting on what he heard from God.
Paul used good judgement.
Firm about the gospel, he took influential leaders aside and spoke with them so as not to argue with them in public. He knew he could convince them but didn’t want them to influence others into disbelief which could make it appear as if he was running in vain.
As believers we are instructed to proclaim the gospel throughout the whole world. But how? It seems like a good and simple formula for us to follow as we live this life and follow the Lord. Listen, then Act, and use Good Judgement.
One thing is certain. Sharing the gospel is a command to us and requires action. The question becomes how are each of us as individuals called to share the gospel. I submit to you that without being quiet and listening for God to speak, through whatever means he speaks to you, you will never know how he is calling you to act.
Further, I think that once we begin to act on how the Lord is directing us, we need to look inward to the Holy Spirit for guidance and judgement based on our strong foundation of God’s Word – pray, study the bible, consult with other strong Christians.
Lord I love you and live to glorify you. Help me to be quiet and listen for you. Help me to discern your voce and guidance from mine and other people. Guide me in how best to apply the gifts you have given me to build your kingdom. In Jesus’ mighty name I pray. Amen.
