Let’s parse this one.  Agape trusts all.

I understand my love for Christ is a love which trusts Jesus in all things in all ways.  Why?  Because He has proven himself trust worthy to me.  I know that even when things seem strange and out of sorts that Jesus has it all under control and eventually it will work out for good.

Romans 8:²⁸ And we know that all things work together for good to them that love God, to them who are the called according to his purpose.

Love requiring trust makes sense to me when it is us loving Jesus.  Why?  Because Jesus is trust worthy.

But turn it slightly, I know Jesus Agape me.  But I am not a trustworthy person at all.  I mean to be.  I really do.  I am like the disciples who kept falling asleep while Jesus prayed.  My spirit is willing but my flesh weak.

Matthew 28:⁴⁰ And he cometh unto the disciples, and findeth them asleep, and saith unto Peter, What, could ye not watch with me one hour?

⁴¹ Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak.

Why would Jesus have any trust in me?  I know He knows I will fail Him.  Yet Jesus loves me with agape love.  Jesus believes in me.  Jesus believes in you.  Jesus spoke about you and about me in his prayer.  He believed in us.  See His words.  He trusted us.

^{John 17:18} As thou hast sent me into the world, even so have I also sent them into the world.

¹⁹ And for their sakes I sanctify myself, that they also might be sanctified through the truth.

²⁰ Neither pray I for these alone, but for them also which shall believe on me through their word;

²¹ That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.

²² And the glory which thou gavest me I have given them; that they may be one, even as we are one:

²³ I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.

²⁴ Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.

²⁵ O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.

²⁶ And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.

We trust Jesus, that is the foundation of our relationship with Him.  We trust him for salvation and we are to trust Him through every stage of our lives.  We see He actually has faith in us that through our walk with Him we will grow towards the perfection of being one with Him and the Father.

But we are also called to have faith in our brothers and sisters in Christ.  We need to show them we have confidence in them.  We know if they hold on tight to Jesus he can do a great work in them.  When they are weak, we may have to help them hold on.  But Agape love trusts.  We are to believe in our fellow Christians just as Jesus believes in us.  They may fail us on occasion, but we are all in this growing process together.  Jesus believes in me even when the flesh is weak.
