But now they are hidden from your eyes.

Luke19:42
If you had known ... in this your day, the things that make for your peace! But now they are hidden from your eyes.

There are things that God reveals to us, and there are things that God conceals from us. Those whom He regards as friends, He will reveal things too. To be considered His friend, depends on our walk with Him. As His children living in this sinful world, we are tempted by various things and falling for those temptations brings us further from God than before. That is why sometimes we fail to see the things God wants to reveal to us. Our hearts may become hardened as we are in denial or preoccupied with whatever sins we are involved in. However, it is not too late to remember that there is no condemnation in Christ Yshua and go back in repentance to Him.

For I have appeared to you for this purpose

Acts 26:16
But rise and stand on your feet; for I have appeared to you for this purpose, to make you a minister and a witness both of the things which you have seen and of the things which I will yet reveal to you.

Paul encountered the risen Lord and his entire life changed. He had only one purpose and that is to do the will of God as revealed in Yshua. The encounter itself may have been short, and Jesus said few words. There was no doctrine or theology being taught, no correction to Paul intellectual knowledge. It was just Yshua revealing Himself. That was enough to change the life of Paul.

Although many of us do not have the Jesus encounter that Paul did, when we believe, the Holy Spirit did come into us. It is not by our own wisdom or understanding that we chose Christ, but He chose us. Having been chosen, we still must will ourselves to live for Christ.

But when it pleased God ....to reveal His Son in me ... I might preach Him

Galatians 1:15-16
15 But when it pleased God, who separated me from my mother’s womb and called me through His grace, 16 to reveal His Son in me, that I might preach Him among the Gentiles, I did not immediately confer with flesh and blood.

Three things to note here is that i) it pleased God ii) to reveal Yshua to us iii) for us to preach His good news to the Gentiles. These three are in fact tied together.

Firstly it is pleasing to God that He has chosen us, not that we decide to choose Him. This is not due to any credit that we might have earned through our practice of goodness. It is His grace that He is pleased to choose us.

Secondly, the revelation of Yshua to us as our Lord, is the highpoint for us. The divine God, also being human, is the substance of our hope - this is object of our faith.

Thirdly, our Lord has a mission to reveal Himself to all the world. We who are followers are not only assigned this task, but it is something natural that we would want to share the Good News that our Lord brings.
